Don't overcrowd the fryer
Leave plenty of room for the chicken - too much chicken and the temperature of the oil/fryer drops too much.
Don't have buttermilk? No problem!
Just substitute with Greek or natural yoghurt. The acids in the yoghurt will tenderise the chicken beautifully.
Keep it warm in the oven
We're not suggesting you keep it warm for hours like they do it a Chicken Shop, but keeping it in a warm oven (75 Degrees Celsius is fine) whilst you fry off more chicken or prepare your sides??? No problem!
