Datterino Cotto nella Calce

**Datterino Cotto nella Calce**

**Datterino Cotto nella Calce** (literally "datterino tomato cooked in lime") is a contemporary Italian dish that transforms the humble datterino tomato through a surprising alkaline cooking process. The technique involves submerging the small, sweet tomatoes in a food-grade calcium hydroxide (lime) solution, which chemically alters their texture and flavor.

**Origin and Technique**

The dish emerged from experimental Italian kitchens seeking to deconstruct traditional tomato preparations. The datterino tomato, a small, oval variety known for its intense sweetness and low acidity, is briefly immersed in a dilute lime solution. This alkaline bath breaks down pectin in the tomato's cell walls, creating a uniquely firm yet tender texture while concentrating its natural sugars. The process also mellows the tomato's acidity, resulting in a creamy, almost dairy-like mouthfeel.

**Key Ingredients and Distinctions**

A great version relies on peak-season datterini, preferably from volcanic soil regions like Mount Vesuvius or Pantelleria. The lime solution must be precisely calibrated—too strong yields a bitter, soapy result; too weak fails to achieve the characteristic transformation. After the lime bath, the tomatoes are thoroughly rinsed and often finished with high-quality extra-virgin olive oil, sea salt, and fresh herbs.

**Regional Variations and Notable Preparations**

In Rome, chef **Marco Baccanelli** at Ristorante Pipero serves his version with burrata cream and basil gel, describing the texture as "a tomato that thinks it's a cheese." On the Amalfi Coast, **La Sponda** at Le Sirenuse pairs the tomatoes with anchovy butter and crispy capers. In Milan, **Alice Ratti** at Contraste offers a cold interpretation with tomato water consommé and shaved bottarga. The dish has also inspired variations using cherry tomatoes or larger heirloom varieties, though purists maintain the datterino's natural sweetness is essential for balance.
