Saving your tomatoes: From storage tips to planting your mouldy ones

The characteristic white coating that appears on a tomato's skin means it is no longer edible. We suggest how to store these vegetables to prevent this. And if it does happen, the tomato doesn't necessarily have to end up in the bin.

Some people still think that cutting out the mould or removing it from the surface of the jam is enough. This is not the right approach.

Experts remind us that any product showing even tiny traces of mould is no longer safe to eat. The visible mould on the surface is just the tip of the iceberg. Such a product also contains mycelium strands that carry health-threatening toxins.

Cutting off the spoiled part is sometimes allowed for dry, hard food, where mould covers only a tiny part. However, it's risky and better avoided. On the other hand, with soft, high-water-content products, you should not attempt to remove the mould, even if the signs are minor. Tomatoes and jam are prime examples of products with which to heed this advice.

Firmer tomatoes, with less pulp, tend to last longer. All soft, fleshy varieties, such as beef hearts or raspberries, spoil faster and, thus, demand special care. It’s generally known that tomatoes shouldn't be stored in the fridge, as they lose flavour in the cold. However, an exception exists for those already soft and overripe; the refrigerator can help prevent spoilage in such cases. Otherwise, room temperature is preferable.

When storing tomatoes in a wicker basket, ensure they aren’t piled directly on each other to avoid bruises, which can expedite spoilage. It is also wise to bring a basket for shopping and carefully arrange the tomatoes to prevent stem damage. Any small puncture in the skin can pave the way for mould.

However, even with the best storage practices, accidents can happen. A tomato showing signs of mould can still be used by planting it in a balcony pot. But first, you need to grow seedlings. Place tomato slices, or rather just the seeds, on moist soil. Initially, ordinary cotton wool will suffice.

The plant needs plenty of water, sun, and warmth to germinate. It's advisable to bring the seedlings inside during cold nights. Once it greens up in the pot, the seedlings should be transplanted, ideally into individual pots. It’s worth a try, as growing your tomatoes can be incredibly rewarding.
