Tomato varieties and best uses

The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common tomato varieties compare.

Variety	Best for
Roma	Sauces, roasting, and slow-cooked dishes; low moisture and few seeds mean it breaks down cleanly.
Cherry	Salads, roasting whole, and snacking; naturally sweet with thin skins.
Beefsteak	Slicing for sandwiches and burgers; large, meaty slices with a mild flavour.
Heirloom	Fresh eating and salads; complex flavour and striking colour, best uncooked.
Grape	Snacking, lunch boxes, and quick salads; similar to cherry but firmer and oblong.

Which should I pick?

Roma is the best choice for sauces and cooking, with firm, low-moisture flesh that holds up well to heat. Use Beefsteak or Heirloom when you need thick slices for fresh eating; Cherry or Grape work well for snacking and salads.
