Mix 1/2 cup yogurt and 2 cups milk in milkshake tumbler. Leave in thermos container, covered in boiled water (We have a yogurt maker). Leave for nearly 24 hours. Voila - yogurt!
Ok, this is not *real* pesto, but we bought a big bunch of basil at the market and we improvised.
Mix bunch of basil with olive oil, garlic, parmesan, sunflower seeds (didn't have pinenuts), pepper, salt, balsamic vinegar. Make a thickish paste.
Glad Matthew's not a whale!
Baby whales drink 500 litres of milk a day.
