Converting Jamie's British Techniques
"Whack it in" = Preheat Fully
US ovens take longer to preheat. Always wait for the beep at 400°F before starting.
"Until golden" = 15-20% longer in US
US ovens often have less powerful broilers. Add 3-5 minutes for browning.
"Bosh" timing = Use a thermometer
Jamie's casual timing works in UK ovens. US: use meat thermometer for accuracy.
Why Jamie's Recipes Might Fail at 400°F
Burning on outside, raw inside
Cause: US ovens run hotter on top
Fix: Move rack to center, tent with foil if browning too fast
Takes longer than Jamie says
Cause: UK gas ovens heat differently
Fix: Add 10-15% to all timing, use 425°F for speed
