Crumble the yeast into a large bowl. Add 150 ml lukewarm water and sugar and mix. Add 5 tbsp. oil, egg white, salt, flour and 1 tbsp. chili flakes and knead with the dough hooks of the hand mixer to a smooth dough. Cover the dough and let it rise in a warm place for about 1 hour
Cut the dough in half. Shape the dough halves into a strand, then divide into about 30 pieces of the same size each. Shape the dough into small balls and roll into thin sticks (approx. 18 cm long) on a work surface (possibly lightly floured).
Spread the Grissini on 2-3 baking sheets lined with baking paper. Bake the trays one after the other in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 15-18 minutes until golden brown. Mix 2 tbsp. oil and 1 tsp. chili flakes. Brush the Grissini with the mixture approx. 3 minutes before the end of the cooking time
Remove the Grissini from the oven and let it cool down. Store in a dry place
Waiting time approx. 1 hour
