The secret of Grandma’s roast beef sandwiches was the Onion Batter Bread.
Grandma's Secret Trick
Grandma sometimes baked this savory bread in a round baking dish and called it "casserole bread." She buttered the baking dish well before adding the dough because this bread sticks more than other yeast breads. When she used glass baking dishes, she turned the oven heat down to 350°F because the crust browns more quickly in glass baking dishes.
A basket of these biscuits graced the table of more covered-dish suppers than we can count.
We were rarely allowed to pick up food with our fingers at the table. This pull-apart loaf was a special exception.
On Sundays we went to Grandma’s to eat pretzels and watch ball games on television.
