Method
Wash and dice the zucchini and yellow squash into uniform 1cm cubes. Dice the onion and celery to a slightly smaller size.
Heat 40ml of olive oil in a large skillet over medium-high heat (approx 190°C/375°F). Add the zucchini and yellow squash in a single layer (do this in batches if necessary to avoid steaming).
Fry the squash for 6-8 minutes until golden brown and tender but not mushy. Remove with a slotted spoon and set aside in a bowl.
In the same pan, add the remaining 20ml olive oil. Add the onion and celery. Sauté over medium heat (160°C/320°F) until softened and translucent.
Stir in the tomato purée, chopped olives, and capers. Simmer gently for 5 minutes to meld the flavors.
Pour in the red wine vinegar and sprinkle the sugar over the mixture. Stir well and cook for 2-3 minutes until the vinegar pungency evaporates and the sauce thickens slightly.
Return the fried zucchini and squash to the pan. Fold gently to coat the vegetables in the sauce without crushing them. Cook for 1 minute to warm through.
Remove from heat and transfer to a serving dish. Let the caponata cool completely to room temperature (at least 1 hour) to allow the sweet and sour flavors to penetrate the vegetables. Garnish with torn mint and toasted pine nuts before serving.
Chef's Notes
- The secret to a great caponata is the 'agrodolce' balance. Taste the sauce before adding the vegetables back in; it should trigger both salivation (sour) and satisfaction (sweet). Adjust vinegar or sugar by 5g increments if needed.
- Do not skip the cooling step. Hot caponata tastes disjointed; room temperature caponata is harmonious.
- For a true finger food experience, serve spoonfuls of this mixture atop toasted baguette slices rubbed with a raw garlic clove.
- If using salted capers, soak them in water for 10 minutes and rinse thoroughly to control the sodium level.
