Background – COVID and the canned tomato shortage

When the COVID Pandemic first hit the shores of Australia and Sydney went into lockdown in March 2020, grocery store shelves were cleared of long shelf life items with a rush of panic buying. Things like pasta, dried beans, rice and all manner of canned goods. While canned tomato was one such item that was always sold out, tomato paste was still widely available. Because canned tomato is a key ingredient in so many recipes, from Bolognese to soups, pasta bakes to stews, pies to curries, I decided to come up with a way to substitute tomato paste for canned tomatoes. To substitute tomato paste for canned tomato, you need to cook it with water and flour to achieve the same consistency and flavour.

How to substitute tomato paste for canned tomato

Mix 4 tablespoons of tomato paste with 1 1/2 cups of water , 1 1/2 tablespoons flour and 1 1/2 teaspoons sugar. It will be watery when “raw” but once added into a dish like Bolognese, it thickens as it cooks (it only takes 3 minutes to thicken). This makes 400 grams (14 oz) which equates to 1 standard can of tomato. And it tastes just like using canned tomato!

How to use it

Use in recipes that call for any canned tomato – diced, crushed – OR tomato passata. Add it at the time the recipe calls for the canned tomato to be added. Cook it just like it’s normal canned tomato!

Just some background info – for those interested!

Why it isn’t just water + tomato paste

Tomato paste is thicker and more sour than canned tomato. And though one might assume you can just use a big dollop of tomato paste + water in the place of a can of tomato, you can’t. You will end up with either:

It’s too thin and the flavour is too weak; or It’s thick enough and tomatoey enough, but it’s way too sour.

So in order to “make” canned tomato using tomato paste, you need to loosen it with water, but then thicken it with flour.

Why you need sugar

Because tomato paste is sour!

Why I’m sharing it now – even though the Sydney lockdown finished months ago

Because sadly, our friends in Victoria have entered into Pandemic Lockdown 2.0 as a result of which people are stocking up, making some popular ingredients like canned tomato difficult to obtain. And a reader specifically asked in my “Pandemic Cooking Hotline” how to use tomato paste in place of canned tomato – so I’m sharing my recipe. I hope you find it useful! – Nagi x
