Spring Radish & Herbed Labneh Tart with Pistachio Crust

What Makes This Special

This elegant tart melds the creamy tang of labneh—a Jewish dairy staple—with fresh spring radishes and herbs, all set in a nutty pistachio crust. The result is a play of textures and flavors: crunchy, silky, sharp, and herbal. Its pale green and yellow palette nods to both spring and St. Patrick’s Day, while refined techniques—like hand-pressed crust and slow-drained yogurt—make it a showstopper for special occasions.

Ingredients

For the Pistachio Shortcrust

Pistachios and cold butter yield a rich, slightly green crust that echoes the Irish theme and pairs perfectly with creamy fillings.

For the Herbed Labneh Filling

Labneh, traditionally made by draining yogurt, gives a tangy, velvety base. Fresh dill, chives, and olive oil add herbal brightness and a nod to both Ashkenazi and Irish flavors.

For the Spring Radish Topping

Sliced radishes offer sharpness, crunch, and color—especially when using a variety of spring types. Lemon and flaky salt enhance their flavor.

Instructions

Step 1: Make Labneh (1-2 Days Ahead)

Line a fine-mesh strainer with 2 layers of cheesecloth and set over a bowl. Stir 3g salt into 750g yogurt. Pour into cheesecloth, tie ends, and refrigerate 24-48 hours until very thick and reduced by half. (Longer draining yields firmer labneh.)

Step 2: Prepare the Pistachio Shortcrust

In a food processor, pulse 120g pistachios to a fine meal. Add flour, confectioners’ sugar, and salt; pulse to combine. Add cold butter; pulse until a coarse meal forms. Lightly beat egg, add, and pulse just until dough clumps. If needed, add ice water 1 tsp at a time. Do not overwork.

Step 3: Blind-Bake the Crust

Press dough evenly into a buttered 23cm tart pan. Chill 30 minutes. Heat oven to 180°C. Line shell with parchment and fill with pie weights. Bake 17 minutes, then remove weights and bake 8-10 minutes more until pale golden and set. Cool completely.

Step 4: Prepare the Herbed Labneh

Scrape labneh into a bowl. Stir in olive oil, lemon zest, dill, chives, and black pepper. Taste and adjust seasoning. Keep chilled until ready to assemble.

Step 5: Prepare Radishes

Using a sharp mandoline, slice radishes paper-thin. Toss with lemon juice and a pinch of flaky salt. Let sit 10 minutes to soften and brighten.

Step 6: Assemble the Tart

Spread herbed labneh smoothly in cooled crust. Artfully arrange radish slices in overlapping concentric circles or loose ribbons. Garnish with parsley, chopped pistachios, and edible flowers if using.

Step 7: Chill and Serve

Refrigerate tart 1-2 hours for flavors to meld and filling to set. Unmold, slice with a sharp knife, and serve chilled.

Pro Tips

• Labneh Texture: For the creamiest filling, drain yogurt for the full 48 hours and press gently to remove excess whey.
• Crust Evenness: Press crust dough firmly and evenly for a crisp, professional finish. Chill before baking to prevent shrinkage.
• Radish Preparation: Use a mandoline for ultra-thin, uniform slices; this ensures a delicate bite and elegant look.

Troubleshooting

Crust Crumbles When Sliced? Too little moisture or overbaking can cause crumbling. Add water sparingly to dough and do not overbake.

Labneh Too Runny? Drain longer, or gently squeeze the cheesecloth to extract more whey before mixing in herbs.

Variations

• Irish Twist: Add finely chopped fresh tarragon or wild garlic to the labneh for a more pronounced Irish herb flavor.
• Beet Carpaccio: Layer thinly sliced golden beets with radishes for extra color and earthiness.
• Egg Garnish: Nestle soft-boiled quail eggs among the radishes for a Passover or Easter-inspired touch.

Storage

Refrigerate assembled tart, covered, for up to 2 days. Crust may soften slightly but flavor improves as it sits. For best texture, assemble the same day as serving.

This tart brings Jewish dairy tradition into a bright spring celebration, harnessing minimal processing to let each component shine. It’s as pleasing to the eye as it is to the palate—perfect for a St. Patrick’s Day feast or refined spring gathering.
