Hot Cabbage and Pepper Slaw Recipe

Core and shred the cabbage. Seed and thinly slice the peppers.
Mix them together in a large bowl; set aside.
Melt the butter in a heavy-bottom saucepan; stir in the flour and cook a minute or two without browning. Whisk in the water and continue cooking until mixture thickens and boils. Remove from heat and beat in the sugar, egg yolks, and salt. Return to heat and boil gently, stirring constantly, for 1 minute more. Whisk in the vinegar, then pour over the cabbage mixture. Toss to coat thoroughly. Best served warm but may also be served chilled.
