by briefly cooking them in boiling water, then rapidly cooling them in ice water to halt the
cooking process.
What is the difference between organic and conventional farming practices?
✔✔Organic farming uses natural methods to grow crops without synthetic pesticides or
fertilizers, while conventional farming may use chemical pesticides and fertilizers to improve
crop yield.
What is the role of gluten in bread-making?
