Ingredients
Directions
Prepare the filling

Season with black pepper.
Make the topping and thicken
Drain and mash the potatoes and butternut squash, seasoning with black pepper.
Blend the cornflour with 1 tbsp cold water and add it to the mince mixture, stirring until thickened.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down into a starchy mash that becomes the crisp, browned topping.
- Butternut squash
- Adds sweetness and moisture to the mash, softening its texture.
- Vegetarian mince
- Provides the meaty bulk and chewy texture of the filling.
- Chopped tomatoes
- Supply acidity and liquid that build the savoury base of the filling.
- Cornflour
- Thickens the filling so it holds together rather than running out.
- Mushrooms
- Add savoury depth and a moist, tender bite to the filling.
The step that matters
Thickening the filling with cornflour. Cornflour must be blended smoothly with cold water first, then stirred into the simmering mixture. Added dry or to a boil-free pan, it clumps, and the starch only thickens fully once the mixture is hot.
