Sieve dry ingredients. Add yogurt to egg mixture and mix in with dry ingredients.
This will make a very solid dough. Use two large greased baking pans. Bake for 55 min or till golden brown. Remove from heat, remove from pans. Let the breads cool slightly. Slice the bread into slices and then cut into fingers. Place on a drying rack and dry in oven on 90 degrees till the rusks are dry and hard.Let them cool off and place in an air tight container.
Serve with coffee, Milo or tea. Dunk the rusks in the hot drink and eat. They are very moreish.
