Cooking And Salad Oil

Dressing shortening is unusual — solid fat at room temp won't suspend in vinegar emulsions, so this use-case targets warm dressings (German potato salad, hot bacon vinaigrette) where the fat melts into hot vinegar at 140°F. Substitutes lean liquid for cold dressings (cooking oil 1:1, avocado 0.75:1) and animal-fat for warm-served (lard 1:1, butter 1:1 melted). Margarine works at 1:1 only when fully melted; solid margarine cubes won't whisk into vinaigrette.
Use 7/8 cup liquid oil per cup shortening; works in quick breads and cakes, not flaky pastry
Use 7/8 cup neutral cooking oil per 1 cup shortening in dressings — liquid oil emulsifies into vinegar with mustard or honey at 1:3 oil-to-acid ratio. Skip for warm bacon or hot potato dressings calling for solid fat at start; for those use lard or butter. Cold dressings: oil at 70°F whisks clean.
Use 3/4 cup liquid oil; best for quick breads
Use 0.75 cup avocado oil per 1 cup shortening in cold dressings — avocado oil's grassy-buttery profile blends with sherry vinegar, lemon, or apple cider. Refined for neutral, virgin for added flavor. Whisk into acid first with mustard or egg yolk; cold-emulsified dressings hold for 4-6 hours before separating in fridge.
Use 3/4 cup oil per 1 cup shortening; works in quick breads and cookies, not flaky pastries
Use 0.75 cup vegetable oil per 1 cup shortening in cold dressings and vinaigrettes — vegetable oil blend (typically soy or canola) at 70°F whisks into vinegar with mustard or egg yolk for stable emulsion. Neutral flavor lets vinegar, herbs, and mix-ins lead. For warm dressings, butter or lard hold heat better than oil.
Use equal amount butter; adds richer flavor and golden color to baked goods and pie crusts
Same solid texture, works well in baking
Same semi-solid consistency
Softer texture; chill before cutting into pastry dough, works 1:1 in cookies and cakes
Adds nutty flavor, slightly softer pastry texture
