What each ingredient does
- Potatoes
- Provide the starchy base that softens inside and browns on the outside when fried.
- Butter
- Conducts heat into the potatoes and adds fat for browning and flavour.
The step that matters
Drain and dry the potatoes with a towel. Surface water must be removed before frying, otherwise the potatoes steam instead of browning and the hot fat can splatter.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
