Preheat oven to 350 degrees Fahrenheit and line two baking sheets with parchment paper.

In a medium bowl, combine the flour, baking powder, and salt. Pour the oil, margarine, and water, and knead until a smooth dough forms. Cut the dough in half.

Knead the caraway seeds into one half of the dough. Working in batches, pinch small balls off the dough. Between your hands, roll out into a long rope and pinch both ends together. Place on the baking sheet. Repeat until both doughs are formed.

Brush each ring with the egg and sprinkle with sesame seeds. Bake, one tray at a time, for 20 minutes or until golden brown the top is crispy. Allow to cool before transferring to an airtight container.

Freezer: Place in an airtight container, wrap with many layers of plastic wrap and store in freezer for up to six months. You can easily double up this recipe.
