Spotlight: The World's Largest Private Citrus Collection and 6 Recipes Worth Trying

Spotlight: Why the Todolí Citrus Collection Matters — and 6 Recipes That Make Rare Citrus Easy

Short on time but craving bold, healthy flavor? If your weeknight routine needs a lift and you’re tired of the same lemon-or-orange choices, this profile of the Todolí Citrus Foundation — plus six practical recipes — is for you. In 2026, chefs and home cooks are turning to rare citrus varieties to solve two problems at once: extraordinary flavor and climate-smart foodways. Below you’ll find the essentials on sourcing and using uncommon citrus, plus recipes that are approachable in a home kitchen.

The headline: Todolí is more than a farm — it’s a living library

The Todolí Citrus Foundation on Spain’s eastern coast is the world’s largest private citrus collection, stewarding more than 500 varieties from Buddha’s hand to sudachi and finger lime. The collection is run as a nonprofit, focusing on biodiversity, organic cultivation and the preservation of rare genetic resources that could be crucial as citrus growers face pests, diseases and climate change.

“The groves have become a haven for frogs, goldfinches and bees,” noted recent reporting — a sign that preserving rare varieties also supports wider farm biodiversity.

Why does that matter in 2026? Agriculture trends this year prioritize resilience, biodiversity, and flavor-led sustainability. As groves worldwide contend with shifting climates and citrus greening disease, collections like Todolí are genetic lifelines and culinary treasure chests for chefs and product developers.

What chefs and food innovators are doing with rare citrus (current trends)

• Culinary experimentation: Top chefs are pairing bergamot and finger lime with seafood and dim-sum–inspired dishes to add precise aromatic acidity.
• Drinks innovation: Mixologists have leaned into citrus sodas and low-sugar cocktails using finger limes and kumquats for texture and aromatics.
• Zero-waste and peel-forward uses: Buddha’s hand and bergamot peels are being candied, zested into confectionery, or distilled for bitters and oils.
• Home-friendly preservation: Marmalades and vinegars made with rare citrus are trending as easy ways to stretch seasonal flavors year-round.

How to source and store rare citrus in 2026

Demand for rare citrus has pushed new supply channels. Here’s how to find and keep them fresh.

Sourcing

• Check specialty markets and Asian groceries for sudachi, yuzu, and calamansi.
• Look to farmer-market vendors or online small-batch orchards; many groves now ship domestically.
• Follow restaurants and bars that list rare citrus on menus — they often sell surplus or point you to growers who participate in pop-ups and micro-events with local producers.

Storage

• Whole fruit: Store in the crisper drawer for up to two weeks; more delicate types like finger limes are best used within a week.
• Zest and juice: Zest and freeze in airtight containers; juice frozen in ice-cube trays preserves brightness for months.
• Peels: Dry or candy peels to preserve aroma and reduce waste — these techniques pair well with small-batch producers who sell peel products at markets using compact payment stations.

6 accessible recipes that spotlight uncommon citrus

Each recipe below is designed for home cooks and includes substitution notes if a specific exotic fruit is unavailable in your market.

1. Finger-Lime Soda — Effervescent, textured, low-sugar

Finger limes deliver citrus pearls that burst with juice — perfect for a soda that feels gourmet but takes 10 minutes to make.

• 2–3 finger limes (or 2 tbsp finger-lime pearls if bottled)
• 250 ml chilled sparkling water
• 2 tbsp honey or agave (adjust to taste)
• Juice of 1/2 lime or sudachi (optional, to boost acidity)
• Ice and a sprig of mint for garnish

1. Halve the finger limes lengthwise and gently scoop out the pearls with a small spoon. If you’re using bottled pearls, measure them out.
2. Stir the honey or agave with the optional lime/sudachi juice in a small bowl until dissolved.
3. Divide ice between two glasses, add finger-lime pearls, a spoonful of the syrup, and top with sparkling water. Stir lightly to distribute pearls, garnish with mint, and serve immediately.

• If finger limes are unavailable, pop a tablespoon of high-quality citrus jam into the glass for a similar sweet-tart effect.
• For a cocktail version: add 30–45 ml gin or tequila per glass.

2. Bergamot Vinaigrette — Aromatic dressing for salads and seafood

Bergamot offers intense floral perfume and bitter-sweet peel notes. A little goes a long way in a vinaigrette.

• 1 tbsp bergamot juice (or 1 tsp bergamot cordial + 1 tbsp lemon juice)
• 1 tsp finely grated bergamot zest
• 3 tbsp extra-virgin olive oil
• 1 tsp Dijon mustard
• 1 tsp honey or maple syrup
• Salt and white pepper to taste

1. Whisk together bergamot juice, mustard and honey. Slowly drizzle in oil while whisking to emulsify.
2. Stir in zest and season with salt and white pepper. Taste and adjust balance — bergamot is more floral, so you may want a touch more acid.
3. Use immediately on microgreens, shaved fennel, or as a finishing drizzle for grilled fish.

• Great with light salads, seared scallops, or roasted beets and goat cheese.

3. Kumquat Marmalade — Small fruit, big flavor

Kumquats need no peeling; their sweet peel contrasts the tart flesh. This recipe keeps sugar modest and uses a pectin-free jam method popular with modern home cooks.

• 500 g kumquats, thinly sliced and seeds removed
• 300–350 g granulated sugar (adjust to taste)
• 150 ml water
• Juice of 1 lemon (or sudachi/yuzu if you want extra floral acid)

1. Place sliced kumquats and water in a saucepan. Bring to a simmer, cover, and cook 15 minutes until peels are tender.
2. Add sugar and lemon juice; simmer gently, stirring, for 25–35 minutes until the mixture thickens to marmalade consistency. Skim foam if desired.
3. Spoon into hot-sterilized jars and seal. Refrigerate after opening.

• Use 150 g sugar and 2 tsp powdered pectin to reduce sugar while keeping set. Adjust acidity to balance sweetness.

4. Sudachi-Cured Fish (quick gravlax-style) — Bright and effortless

Sudachi is intensely aromatic and tart; it’s perfect for a quick citrus cure that keeps the fish delicate.

• 500 g sushi-grade salmon or sea bass fillet, skin on
• Zest of 1 sudachi (or 1 lime + 1 tsp yuzu juice)
• 2 tbsp coarse sea salt
• 2 tbsp sugar
• 1 tsp crushed black pepper
• Optional: 1 tbsp finely chopped dill or shiso

1. Mix salt, sugar, pepper and zest. Pat fish dry and rub mixture evenly over flesh. Sprinkle chopped herbs if using.
2. Place fish in a shallow dish, cover, and weight with a plate. Refrigerate 12–18 hours for a quick cure.
3. Rinse briefly under cold water, pat dry, and slice thinly across the grain. Serve with steamed rice, rye toast, or on salads. Finish with microgreens and a drizzle of bergamot vinaigrette if you like.

If sudachi is scarce, use equal parts lime and yuzu, or lime + a touch of grated orange peel for a different aromatic profile.

5. Buddha’s Hand Olive Oil Cake — Citrus perfume without juice

Buddha’s hand has little to no flesh — it’s all fragrant peel and pith. Use its zest to perfume a moist olive-oil cake that’s deceptively simple and impressive.

• 200 g plain flour
• 150 g caster sugar
• 3 eggs
• 120 ml extra-virgin olive oil (mild, fruity type)
• 80 ml whole milk or yogurt
• 2 tsp baking powder
• Grated zest of 1 medium Buddha’s hand (or 1 large bergamot)
• Pinch of salt

1. Preheat oven to 170°C. Grease and line a 20 cm loaf tin.
2. Beat eggs and sugar until pale and slightly thickened. Slowly whisk in olive oil and milk/yogurt.
3. Sift in flour, baking powder and salt. Fold gently to combine, then stir in the zest.
4. Pour into tin and bake 35–40 minutes until a skewer comes out clean. Cool slightly, then remove from tin and serve warm or at room temperature with a dusting of powdered sugar or a thin glaze of bergamot juice and icing sugar.

This cake shines with tea, coffee, or a citrus-forward white wine. It’s also a terrific make-ahead item for brunch or a picnic. For guidance on choosing and storing pantry oils used in recipes like this, see Sustainable Oils in Your Pantry.

6. Kumquat & Bergamot Cocktail — Bright, bitter, and aromatic

This low-sugar, high-aroma cocktail riffs on classic bitter-sour templates: kumquat for texture and bergamot for perfume.

• 4–6 kumquats, halved (or 30 ml kumquat puree)
• 45 ml gin or blanco tequila
• 15 ml bergamot liqueur or 10 ml bergamot juice + 5 ml simple syrup
• 15 ml Aperol or similar bitter aperitif (optional)
• Ice and a sprig of rosemary or thyme

1. Muddle kumquat halves in a shaker to release oils and juice. Add spirits, bergamot component and Aperol if using. Fill with ice.
2. Shake vigorously, then double-strain into a chilled coupe or rocks glass over a large ice cube.
3. Garnish with a sliver of bergamot peel or a sprig of herb. Sip slowly to enjoy the aromatics.

Replace alcohol with 60 ml chamomile tea and 20 ml tonic, retaining the bergamot and kumquat elements for complexity.

Practical kitchen science: making the most of uncommon citrus

• Zesting technique: Use a microplane for oils; avoid the white pith which is bitter unless the recipe calls for it.
• Balancing acid: Many rare citrus are more floral and less sour than lemons. Pair them with a brighter acid (lime, sudachi, or a splash of vinegar) if you need lift.
• Peeled vs. whole: For marmalades and preserves, thin-slicing whole small citrus (kumquat, calamondin) keeps peel-to-flesh ratios balanced.
• Texture tricks: Finger-lime pearls add sensory pop. Store pearls in salt syrup if long-term preservation is needed.

Why home cooks should embrace rare citrus in 2026

Beyond novelty, rare citrus varieties deliver practical benefits: they concentrate intense aromas so you often need less fruit; their unique flavor profiles unlock new pairings; and choosing them supports biodiversity-friendly growers who sell at markets, pop-ups and through direct channels. In 2026, new collaborations between culinary professionals and conservation farms are accelerating—chefs are partnering with collections to trial varieties that might withstand future pests and droughts.

Actionable takeaways: quick checklist before you cook

• Buy one rare citrus and plan three uses: one raw (soda or garnish), one cooked (marmalade or cake), and one for preservation (vinegar, cured fish or candied peel).
• Zest first, juice second. Zest stores better frozen and preserves the volatile oils.
• When substituting, match aromatic intensity more than type: bergamot → bergamot cordial or bergamot-infused syrup; finger lime → citrus pearls or finely diced jalapeño for texture contrast (if you want a textural pop).
• Support producers: buy from small orchards or markets that list farm provenance, and try to buy in-season to maximize flavor and minimize carbon footprint.

Final thoughts — flavor, resilience, and a small promise

Collections like the Todolí Foundation are living reminders that flavor diversity and agricultural resilience go hand in hand. As you try bergamot marmalade or sudachi-cured fish, you’re participating in a food trend that’s both delicious and responsible.
