I always used to have trouble with risottos until my friend passed on this recipe:
Smoked tuna risotto
2oz/60gms risotto rice per person to 1/2 pint of stock made with a single veggie oxo cube
1/3 of a pepper, small onion, carrot (any veg really) per person
Lazy Chilli (the stuff in those square jars)
Garlic
splash olive oil
Smoked tuna (you can buy in cans, but smoked or peppered mackerel also is delish)
Tomato
Heat the olive oil & one the rice starts to bubble when you drop in a single grain add the rest of the rice & stir continuously for 2 mins. Add the onion, chilli & garlic & stir for a further 2 mins. Add the veg (cooked or uncooked, so great for leftovers), and the stock, bring to simmer & cover. Leave for about 20 minutes. Just before serving add the tuna & tomato, stir through until cooked/heated.
Serve.
It is really tasty & seems so far to be pretty foolproof!
