British Mushy Peas (Using Regular Spring Peas) - cooking recipe

Ingredients

1 kg frozen peas, rinsed (regular English peas or spring peas)
40 g unsalted butter
2 teaspoons salt (to taste)
pepper, to taste
10 g of fresh mint (a small handful of leaves)

Preparation

Heat some water in a saucepan to boiling, then add the peas and cook for about 5 minutes until tender.
Drain, but save about 200 ml of the cooking water.
Puree in a blender ( or use a stick blender) with butter, mint leaves, salt & pepper to taste, and some of the reserved cooking liquid (adding as much or as little as you feel you need - you want it kind of pasty and gloppy, like loose mashed potatoes).
Leave a few chunks. Test for seasoning and adjust as needed.
Reheat gently in saucepan if needed.
