Set up safely
Clean the board, pan, and utensils before starting Caramelised Onion Jacket Potatoes. Check labels on baking potatoes, onions, cheddar, plus any sauces, stock, spice blends, and toppings.
This is the step that prevents most accidental gluten exposure.
- - Check sauces, stocks, spice mixes, sausages, cornflakes, oats, baking powder, and specialist free-from products every time because labels change.
- - Use clean boards, pans, colanders, toaster bags, and utensils if the kitchen also handles wheat.
