Cherry tomatoes in brine are a short summer ferment with a beautiful balance of sweetness, salt, acidity, and herb fragrance. The tomatoes soften slightly, the garlic becomes mellow, and the basil gives the brine a warm, Mediterranean character.
This is not a long pantry preserve. Cherry tomatoes are delicate and juicy, so they are best fermented briefly and stored in the fridge once they taste bright and lightly tangy.
Use firm, ripe cherry tomatoes with unbroken skins. A tiny prick in each tomato helps the brine reach the inside and reduces the chance of the tomatoes bursting unpredictably.
Why you’ll love this ferment
Cherry tomatoes in brine are simple but full of character. They are juicy, savoury, gently tangy, and aromatic.
Serve them with cheese, roasted vegetables, rice bowls, pasta salads, toast, eggs, flatbreads, or mezze-style plates. You can also spoon the tomato-scented brine into dressings or sauces.
FAQs
Do I need to prick cherry tomatoes before fermenting?
Yes, it is helpful. Pricking each tomato once allows the brine to reach the inside and can reduce bursting. Use a clean skewer or toothpick.
Why are my cherry tomatoes floating?
Cherry tomatoes naturally float because they trap air and have firm skins. Use a fermentation weight to keep them below the brine. Any exposed tomatoes may spoil.
Can I use other herbs instead of basil?
Yes. Oregano, thyme, parsley, or dill can be used, but basil gives the most summery tomato-friendly flavour. Tender herbs may darken in the brine, which is normal.
Cherry Tomatoes in Brine
Ingredients:
For 1 litre jar:
- 500 g firm cherry tomatoes
- 2 garlic cloves, peeled and lightly crushed
- 6–8 fresh basil leaves
- ½ tsp black peppercorns
- 500 ml water
- 15 g fine sea salt or pickling salt
Brine Ratio
This recipe uses a 3% brine:
Directions:
- Wash the cherry tomatoes and basil well.
- Use a clean skewer or toothpick to prick each tomato once. This helps the brine penetrate the skins.
- Place the garlic, basil, and black peppercorns in a clean 1 litre jar.
- Add the cherry tomatoes gently, taking care not to crush them.
- Dissolve the salt fully in the water. Pour the brine over the tomatoes until they are fully covered.
- Use a fermentation weight to keep the tomatoes below the brine. Cherry tomatoes float easily, so this step is important.
- Close the jar loosely, or use a fermentation lid. Place the jar on a small plate.
- Ferment at room temperature for 2–4 days. In warm weather, taste after 48 hours.
- When the tomatoes are lightly tangy and the brine smells fresh and savoury, transfer the jar to the fridge.
What to Expect
The brine may become lightly cloudy and small bubbles may appear. The tomatoes may soften and some may split. This is normal, as long as the ferment smells fresh and pleasant.
The basil may darken in the brine. This is also normal.
Discard the ferment if you see mould, unpleasant odours, slimy texture, or signs of spoilage.
Fermentation Time
2–4 days at room temperature.
In hot weather, check early.
Notes:
Storage
Store in the fridge and use within 1–2 weeks.
Use clean utensils and keep the tomatoes covered by brine.
Serving Ideas
Serve with fresh cheese, toasted bread, roasted vegetables, lentils, rice, eggs, or pasta salad.
Spoon over grain bowls with olive oil and herbs.
Chop into a quick relish with extra basil and a little olive oil just before serving.
Use the brine in small amounts in salad dressings or sauces where a salty tomato note would be welcome.
