—Take egg yolks, draw them through a strainer, cast fair flour, barm and ale thereto, stir it together until it is thick. Take pared apples, cut them thin like obleies (these are small cakes or wafers, often defined as "sacramental wafers"), lay them in the batter; then put them into a frying pan and fry them in fair grease or butter until they are yellow-brown; then put them in dishes, and straw enough sugar on them, And serve them forth.
Apple Fritters (test sized batch)
Make a batter from:
-2-3 egg yolks whisked until light
-1 package of yeast (2 1/4 tsp) softened in about 3(liquid)oz of water with a little sugar
-about 1(liquid)oz of ale
-2 1/2 oz of flour
This should make a batter sticky enough to stick to the apple slices. If the batter is too thin, add more flour, if it is too thick, add a bit more ale.
Have your apples peeled and cored and then slice them fairly thin and lay on a towel
Heat clarified butter in a deep pan.
Lay your apple slices in the batter and then carefully place the battered apple rings in the hot fat.
Cook the fritters until golden brown
Lay your fritters in dishes and sprinkle with sugar and serve
(added note: depending on if you used packaged yeast, or home-made style yeast (use about 6 spoonfulls instead of yeast/water mix btw), and the age of the yeast... if it is left to sit too long, it will froth up considerably)
