2 large onions
1 cup cream
1/2 teaspoon salt
1/4 teaspoon pepper
1 egg yolk, beaten
1 head cauliflower
1 slice bread
1 teaspoon butter
Onion Sauce
Remove outer layer from onions, slice and place in a saucepan. Cover with water, and using high heat bring to a boil. Reduce and cook until tender about 15 minutes. Drain, then press through a sieve or puree (I used a Foley mill.) Combine onion puree, cream , salt, pepper, and egg yolk in a saucepan. Using medium heat, heat until the sauce thickens and is on the verge of boiling. Remove from heat.
Cauliflower
Cut the florets from the head of cauliflower. Place in a saucepan, and cover with water. Bring to a boil, then reduce heat and cook until tender (about 8 -10 minutes). Remove from heat and drain.
Bread Cubes
Cut bread into 1/2 inch cubes. Melt butter in small skillet using medium heat, add bread crumbs. Gently stir occasionally until lightly browned. Remove from heat.
To Serve
Place cauliflower in serving dish. Pour onion sauce over the cauliflower, then sprinkle with sauteed bread crumbs.
