Select your substitute according to the desired texture and flavor for your dish.
Prepare by washing and drying leaves thoroughly; chop or tear to match original size.
Use the specified ratios: 1:1 for most substitutes by volume or leaf count; for the DIY blend, mix romaine and butter lettuce 50/50.
Adjust seasoning and dressings as needed to balance any changes in bitterness or sweetness.
Use substitutes promptly; softer lettuces like butter lettuce and spinach wilt faster under heavy dressings or warm ingredients.
