Hi,

don't know if this is the recipe you are looking for:

Quick Potato Sponge Bread

6 eggs, separated
2 tbs. sugar
1 1/4 cup Potato Flour
2 tsp. GF baking powder  (* See note)
1 tsp. salt
1 tbs. sesame seeds

In small bowl beat egg whites and sugar to stiff but moist peaks.  In medium
bowl beat egg yolks on high speed of electric mixer until thick and light,
about 5 min.  Combine potato flour, baking power and salt.  Alternately
whisk dry ingredients and egg whites into yolks, ending with egg whites.
Pour batter into greased 81/2 x 41/2 loaf pan.  Sprinkle sesame seeds evenly
over the batter.  Bake in preheated 350F oven for 40 - 45 min., or until
toothpick inserted in centre comes out clean.  Cool on rack 1 hour.  Remove
from pan; cool completely before slicing.

Hope you like it. Clelia
