Double tomato concentrate Ristoris 800 g at a glance
This Ristoris double tomato concentrate is a dense, bright red paste of Italian tomatoes with a dry residue of about 28 to 30%, packed in an 800 g can (box of 6). Made from only tomatoes and salt, it intensifies the colour and umami of sauces, ragù and braises with a small dose. As a double-strength concentrate it is roughly twice as strong as single concentrate, so half the quantity delivers the same depth of flavour.
What is double tomato concentrate?
Double tomato concentrate is ripe tomato that has been milled, sieved to remove skins and seeds, and reduced until the water content drops and the soluble dry residue reaches 28 to 30%. The result is a thick, deep-red paste used as a seasoning rather than a sauce base. Because the flavour is concentrated, it is dosed by the spoonful and stirred into a fat or liquid, not used like passata or chopped tomatoes.
Ristoris, Italian food-service tomatoes
Ristoris is an Italian food-service brand based in Broni, in the province of Pavia, supplying pizzerias, restaurants and collective catering. Its tomato range is made with Italian raw material and packed in catering formats. The 800 g can is sized for professional kitchens that use concentrate daily to build colour and savouriness into high-volume sauces, soups and braises.
How to use it in a professional kitchen
Toast a spoonful of concentrate briefly in the soffritto or cooking fat before deglazing with stock, water or red wine: this removes the raw acidity and develops a rounded, savoury base. A rule of thumb is about two tablespoons of concentrate per cup of liquid; for the double concentrate use roughly half a teaspoon where a recipe calls for one teaspoon of single concentrate. Add it early in long braises and ragù for depth, or use small amounts to lift quick pan sauces.
Storage and dosing
Store the sealed can in a cool, dry place; unopened it has a long ambient shelf life. Once opened, transfer the unused paste to a container, cover the surface with a thin film of oil, refrigerate and use within a few days. The concentrate is already savoury, so taste before adding extra salt to avoid over-seasoning the dish.
Common mistakes to avoid
Do not use the concentrate raw or undiluted as if it were passata: it stays sharp and acidic and overpowers a dish. Avoid scorching it alone over high heat, which turns it bitter, and resist over-dosing, since the double strength means a little goes a long way. Finally, account for its saltiness when seasoning the finished sauce.
