Method
Pour the vegetable stock into a medium saucepan and bring to a gentle simmer at 90°C/195°F over low heat. Keep it warm throughout the cooking process.
Drop the podded broad beans into boiling water for 2 minutes. Remove with a slotted spoon and immediately plunge into a bowl of ice water. Once cool, pinch each bean to slip off and discard the tough, pale outer skin.
Add the sliced runner beans to the same boiling water for 3 minutes until just tender-crisp. Transfer to the ice water to halt cooking, then drain completely and set aside with the prepared broad beans.
In the wide heavy-bottomed pan, heat the olive oil and 15g of the butter over medium heat. Add the diced shallots and sweat for 5 minutes until soft and translucent, then add the minced garlic and cook for 1 more minute.
Increase the heat slightly and add the arborio rice to the pan. Stir continuously for 2 minutes to toast the grains until the edges turn translucent and the center remains opaque.
Pour in the white wine. Stir vigorously and scrape the bottom of the pan to deglaze, cooking until the liquid has completely evaporated and the alcohol scent has dissipated.
Begin adding the hot stock one ladleful at a time. Stir frequently to coax out the starches, allowing each addition of stock to be mostly absorbed before adding the next. Continue this process for about 18 to 20 minutes.
When the rice is al dente and has a loose, flowing consistency, fold in the blanched broad beans and runner beans. Cook for 1 minute just to warm the vegetables through.
Remove the pan entirely from the heat. Vigorously beat in the mascarpone, grated vegetarian parmesan, remaining 15g of butter, lemon zest, and chopped mint. This step, known as mantecatura, emulsifies the fats and starches into a rich sauce.
Taste and adjust seasoning with fine sea salt and freshly cracked black pepper. If the risotto has tightened up too much, stir in a final splash of hot stock to loosen. Ladle immediately into warm, shallow bowls.
Chef's Notes
- The secret to perfect risotto lies in the mantecatura phase. Beating cold fats into the hot, starchy rice off the heat creates a stable emulsion that yields a glossy, restaurant-quality finish.
- Do not skip heating your vegetable stock. Adding cold stock drops the temperature of the pan, shocking the grain and causing the exterior to turn mushy before the interior can cook.
- Runner beans can be quite fibrous if they are large. Ensure you remove the tough strings running down the seams before slicing.
- If vegetarian compliance is critical, check your cheese label carefully. Authentic Parmigiano-Reggiano legally requires animal rennet, so you must specifically source a vegetarian hard cheese alternative.
Storage
Refrigerator: 3 days — Store in an airtight container. Reheat gently on the stovetop with a splash of water or stock to restore creaminess.
Reheating: Stovetop over low heat with additional liquid
