Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Pork leg
Forms the main body of the dish, and its meat and fat carry the flavour and juiciness.
Ground sage
Adds a savoury, herbal aroma that flavours the meat's surface.
Butter or olive oil
Adds fat that helps the outside brown and crisp in the oven.
Flour (in the method)
Helps form a dry coating that browns and crisps on the roasted surface.
Vinegar
Adds a sharp acidity that brightens the seasoning on the meat's surface.

The step that matters

Keeping the cloth damp while the pork stands. A damp cloth slows surface drying while the salt and seasonings work into the meat. If the cloth dries out, the surface can dry and toughen, so it needs checking during the several hours of rest.

Swap the sage

How well each one fits the dish's main ingredients (pork, butter, vinegar, pepper):

  1. Thymefits about as well
  2. Sagethe original
  3. Tarragonfits about as well
  4. Parsleyfits about as well

Fit is the average pairing score against pork, butter, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
