- 2 shallots
- 1 rib celery
- 1/4 cup unsalted butter
- 1 tablespoon olive oil
- 1 1/3 cups risotto rice, preferably Arborio or Vialone Nano
- Approximately 1 quart vegetable stock
- 1/2 unwaxed lemon, zested and juiced
- Needles from 2 small sprigs fresh rosemary, finely chopped
- 1 egg yolk
- 4 tablespoons grated Parmesan, plus more, for garnish
- 4 tablespoons heavy cream
- Good grating black pepper, preferably white
- Maldon or other sea salt, to taste
Put the shallots and celery into a mini food processor and blitz until they are finely chopped. Heat half the butter, the oil and the shallot and celery mixture in a wide saucepan, and cook to soften the mixture for about 5 minutes, making sure it doesn't stick. Mix in the rice, stirring to give it a good coating of oil and butter. Meanwhile, heat the stock in another saucepan and keep it at the simmering point.
Put a ladleful of the stock into the rice and keep stirring until the stock is absorbed. Then add another ladleful and stir again. Continue doing this until the rice is al dente. You may not need all of the stock, equally, you may need to add hot water from the kettle.
When the risotto is ready - when the rice is no longer chalky, but still has some bite - take it off the heat and add the bowl of eggy, lemony mixture, and the remaining butter and salt, to taste. Serve with more Parmesan if you wish, check the seasoning and dive in.
