The most delicious side dish

Boil a cauliflower with a few cloves of garlic until soft.  When cooked, add a small bag of frozen peas. Cook until peas are done. Strain, and put into a food processor. Add a tablespoon of butter, some concentrated chicken stock, and a few sprigs of fresh tarragon. Blend until incorporated. Add milk as needed. When thoroughly blended, add 1 cup of shredded parmesan, the juice of half a lime and freshly ground black pepper.

So.

Good.
