Boston Roast

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Chop the cooked beans.

  2. Add the grated cheese, chopped onion, and milk; mix well.

  3. Stir in enough bread crumbs to form a roll.

Bake and serve

  1. Bake at 400°F (200°C) for 20 minutes, basting twice with vegetable oil.

  2. Serve with tomato or brown sauce.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Cooked beans
Form the bulk of the roll and give it a hearty, substantial texture.
Grated cheese
Adds richness and fat, helping bind the mixture and add savoury flavour.
Onion
Adds aroma and savoury sweetness as it softens during baking.
Milk
Adds moisture so the mixture holds together without drying out.
Bread crumbs
Absorb moisture and help the mixture set into a firm, sliceable roll.

The step that matters

Stir in enough bread crumbs to form a roll. Too few crumbs leave the mixture wet and likely to fall apart when baked or sliced. Too many make it dry and dense. Add them gradually until the mixture just holds its shape.

Swap the onion

Fit is the average pairing score against beans, cheese, milk, bread. Candidates are from the same food group and used in at least 100 recipes.
