Place a large frying pan over medium heat. Add the butter and let it melt for 1–2 minutes. Add the shallot, garlic and salt and cook, stirring, for 2–3 minutes (watch it doesn’t colour too much). Stir through the tomato paste, then add the vodka and incorporate into the sauce for 2 minutes. It should just be bubbling (so the alcohol cooks out). Add the stock and cream, turn the heat down to a gentle simmer and cook for 10 minutes.
3 tbsp butter, 1 shallot, 3 cloves garlic, pinch sea salt, 0.75 cup tomato paste, 0.25 cup vodka, 1 cup chicken stock, 1 cup thickened cream
