The Look of a Perfect Lychee
Before we can spot a bad lychee, we need to know what a good one looks like. A perfect, fresh lychee is a feast for the senses. Its skin should be a vibrant pink or reddish colour, though some varieties may have hints of yellow or orange. The fruit should feel
heavy for its size, which indicates it's full of juice. When you gently press it, the shell should be firm but have a slight spring to it. It should not feel hard like a rock or overly soft and mushy. A fresh lychee will also have a distinctly sweet, floral aroma. This combination of bright colour, firm-yet-springy texture, and a beautiful fragrance is the hallmark of a lychee at its peak.
Decoding the Brown, Shrivelled Shell
The headline gets it right: a brown, shrivelled shell is a major red flag. A lychee's skin, also known as the pericarp, is thin and porous. Its primary job is to protect the juicy flesh inside, but it loses moisture very quickly after being picked. This process is called desiccation, or simply, drying out. As the shell loses water, it begins to turn brown and shrink, leading to that shrivelled appearance. This is the most common sign of age and deterioration. While a few small brown spots might just be cosmetic, widespread browning means the fruit is well past its prime. The dehydration that causes the shell to brown will eventually affect the flesh, making it less juicy and flavourful.
More Than Just Skin Deep
While the shell is your first clue, there are other signs to watch for. A lychee that feels mushy or soggy has likely gone from overripe to rotten. Any cracks or leaks in the shell are also bad news, as they can be entry points for mould and bacteria. Another powerful indicator is the smell. If your lychee smells sour, acidic, or has a fermented, alcohol-like odour, it has started to spoil and should not be eaten. Once you peel it, the flesh inside should be translucent and whitish. If the flesh is discoloured, slimy, or looks unusually watery, it's best to discard the fruit.
Your Guide to Market-Fresh Lychees
Shopping for lychees doesn't have to be a gamble. Use your senses to pick the best of the bunch. First, look for fruits with vibrant, uniformly coloured skin and a diameter of at least one inch. Avoid any with significant brown patches, cracks, or mouldy spots. Next, gently pick one up. It should feel plump and firm, giving just a little under pressure. If it's hard, it might be underripe; if it's squishy, it's overripe. Finally, give it a sniff. A fresh, floral fragrance is what you're looking for. A sour or vinegary smell means the fruit is fermenting. Remember that lychees do not ripen after being picked, so what you buy is what you get.
How to Store Lychees for Lasting Flavour
Lychees have a notoriously short shelf life. At room temperature, they will start to deteriorate within two to three days. To keep them fresh for longer, proper storage is key. The best method is refrigeration. Place your lychees, unpeeled, in a plastic bag or an airtight container and store them in the fridge. Some experts suggest wrapping them in a paper towel first to absorb excess moisture. This can extend their freshness for up to a week, and sometimes longer. It's important to note that the shells may still turn brown in the cold, dry air of the refrigerator, but this is often just a cosmetic change and the fruit inside should remain juicy and delicious.
