Oven-Dried Tomatoes

The first thing I consider whenever I cook something is: where is the flavour coming from? If it is a risotto the quality of the stock is crucial; if I am making a curry then the spices in the curry paste are the most important elements for flavour, and when making a tomato sauce the quality of the aromatics (not to mention the tomatoes) is key. Get that first consideration wrong, and it won’t matter what else you do, your dish won’t be as delicious as it could possibly be.

I long ago got into the habit of using fish sauce as a way of delivering ‘umami’, and if that isn’t appropriate then an anchovy fillet or two cooked in oil until it all-but dissolves will do the job. If you are making a dish for a vegan though, neither of these methods is appropriate, so I started using commercial sun-dried tomatoes to intensify flavours.

Anyone who knows me knows that I shy away from anything commercially processed, so will know what came next: of course, I started to dry my own tomatoes. It is a simple process, and delivers such intensity to any tomato-based sauce that you will never need to add tomato puree to anything ever again. I now use oven-dried tomatoes in all my tomato sauces, using one or two per tin of chopped tomatoes – so if a recipe calls for two tins of chopped tomatoes, I will augment it with two or four chopped dried tomatoes, depending on the intensity that I require.

They are also lovely spread on toasted bruschetta, with a little goat’s cheese as an antipasti.

To make oven-dried tomatoes:

Heat your oven to 140C/ gas 1.

Cut ripe tomatoes in half and scoop out the seeds, toss the tomato flesh in a little olive oil (I put a couple of tablespoons of olive oil in a large freezer bag, add a kilo of seeded tomatoes and work the tomatoes around the bag so they are fully coated) then lay the tomatoes in a single layer on a rack, set over a baking tray.

Just pop them in the oven and leave them for 2 to 3 hours, until they are reduced in size by about a third. At this point they will still be quite plump, you can go even further and leave them in the oven for up to eight hours so they are fully dried out and leathery. Cooked this way they can be stored almost indefinitely in the fridge.

Pack a kilner jar (or similar) with the dried tomatoes, cover completely with olive oil and store them in the fridge. I have had a jar of plump-dried tomatoes in my fridge for months and they are still perfect, so I have no idea how long they will actually last – long enough, that’s for sure.

If you completely dry your tomatoes then in most cases they can be stored dry, but will need to be re-hydrated in water overnight before use.
