Step #1 Blend all ingredients for the creamed butter to a fine, soft, spreadable consistency (salt & pepper to taste).
Step #2 With a small knife, make a small cross in the base of each tomato.
Step #3 Plunge the tomatoes into a pan of boiling water & count to 20.
Step #4 Remove them to a bowl of cold water, drain & peel off the skins.
Step #5 Butter 10 slices of bread with the creamed butter.
Step #6 Quarter the tomatoes & remove the seeds, press the petals flat & lay them on the slice of buttered bread.
Step #7 Do not layer the tomatoes, as they will cause the sandwiches to come unstuck.
Step #8 Salt & pepper the tomatoes & then press a second slice of bread firmly on to the top of the sandwich, crust & cut into appropriate shapes (should make 30 fingers or 40 squares or quarters).
