Instructions

Bichak are popular appetizers for tea or coffee hour. The pumpkin & jam stuffings are on the sweet side while meat & cheese are savory & could be eaten for lunches w/salad & dish of yoghurt. An added attraction is that they may be prepared in large quantities, cooled & frozen for the future. Heat oil in a pan, add onions, & saute over moderate heat until onions turn golden. Add water, salt, sugar, & squash or calabasa or pumpkin & bring to a boil. Cover pan & cook over low heat for abt 20 mins as squash/calabasa/pumpkin becomes soft & disintegrates. Stir now & then, which in effect mashes contents. Continue last mins of cooking, uncovered, to evaporate all liquid & create & thick jam. The mash is still moist. MEAT: Heat oil in a skillet & brown onions lightly over moderate heat. Add meat, salt, & pepper & stir-fry for 5 mins, making certain liquid has evaporated & mixture is dry. Cool. CHEESE: Mix everything together. Set aside. JAM: Mix jam & crumbs together. Set aside. TO PREPARE TRICORNERS: 1. Mix 1/2 c warm water, sugar, & yeast together & proof in a warm place until mixture foams, abt 10 mins. 2. Make a well in flour, add yeast mixture, oil, & 1 egg white, & stir them into flour. Add balance of water, or enough water to prepare a soft dough. Knead for several mins & roll into a ball. Oil top lightly & leave dough in mixing bowl. Cover bowl w/foil or a towel & let rise for 45 mins to 1 hour. 3. Punch down dough ball. Pull off abt 1/2 cup of dough & roll into a slightly flattened ball. Prepare 6 balls. 4. On well-floured board roll out each ball, 1 at a time, to 12-" pancake. Using empty can or a cookie cutter, 3-" in diameter, cut out circles in pancake. Put 1 tb of whichever stuffing you are using, or variety of stuffings, in center of each circle. Fold over right & left side of circle to meet in the center & bring up bottom to cover stuffing. Pinch ends together to form tricorner pastry. Seal in contents. Paint tops of bichak w/egg yolk.
