Preheat the oven to 200 °c (180 °fan/ Gas 6).
Slice the cabbage leaves into large pieces (discarding any hard woody parts). Bring a pan of salted water to the boil, then cook the cabbage for 3 minutes until tender. Drain, pat dry with a piece of kitchen roll, and set aside to cool slightly.

Add the flour and stir for 2 minutes.
