Street-Food Comfort, Made at Home

Walk down almost any soi in Thailand in the late afternoon and you will smell them before you see them: bananas dipped in batter and dropped into hot oil, the air turning sweet and nutty as the shells puff and crisp. Gluay tod — Thai banana fritters — are sold in paper bags, sometimes threaded onto bamboo skewers, always eaten scalding hot with the inside molten and soft. They are one of the great arguments for frying at home.

The good news is that they are forgiving, quick, and made from things you almost certainly have already. The batter takes five minutes, the frying takes three, and the result is far lighter than the doughnut-style fritters you might be imagining. Get the banana right, keep the batter cold, and you will be eating proper Thai street food in your own kitchen before the kettle boils.

Choosing the Right Bananas

This is where most home cooks go wrong. A speckled, fully ripe banana is wonderful for banana bread and disastrous here: it collapses under heat, releases steam through the batter and turns the crust soggy while spitting ferociously in the oil. You want fruit that is firm, just-yellow, with perhaps a trace of green at the stem. Slightly underripe is far better than slightly overripe.

Thai cooks favour small, dense varieties — nam wa in Thailand, saba in the Philippines. In the UK, look for baby bananas or "apple bananas" in Asian grocers; they hold their shape and taste faintly of pineapple. Otherwise, a firm Cavendish does the job perfectly well.

• Small dense bananas: 8–10, peeled and halved lengthways, or left whole if very small
• Firm Cavendish: 4 large, cut into 5cm diagonal chunks so more surface area meets the batter
• Avoid: any banana that squashes under gentle pressure — no amount of batter will rescue it

The Batter: Cold, Thin, Sesame-Flecked

Rice flour is the secret to that glassy, shattering crunch. It contains no gluten, so it fries hard and brittle rather than chewy, while a smaller proportion of plain flour gives the shell enough structure to cling to the fruit. A spoonful of sesame seeds goes straight into the batter, where they toast in the oil and add a savoury, peanutty edge that stops the whole thing becoming sickly.

For roughly four servings, whisk together 100g rice flour, 50g plain flour, 1 tsp baking powder, 1 tbsp caster sugar and a good pinch of salt. Stir in 1 tbsp white sesame seeds, then add cold water a little at a time — around 180–200ml — until you have something the consistency of double cream. It should coat the back of a spoon and ribbon off it. If you want a richer, more coconutty shell, replace half the water with coconut milk, but be aware it darkens and burns a touch faster.

Keep that bowl cold. Sit it in a larger bowl of iced water if your kitchen is warm, and only dip bananas as you are ready to fry. Warm batter slides off the fruit and drinks up oil.

Frying Without Fear

Use a deep, heavy saucepan and about 5cm of neutral oil — groundnut or rapeseed are ideal. Heat to 170–180°C. Without a thermometer, drop in a cube of stale bread: it should brown in about thirty seconds, not instantly blacken and not sit there pale and greasy.

Pat the banana pieces dry, dip them in the batter, let the excess drip back into the bowl, and lower them gently away from you. Fry in small batches — three or four pieces at a time — because crowding drops the oil temperature and gives you pale, oily fritters. Turn once, after about ninety seconds, and cook until deep golden and blistered, roughly three minutes total.

Drain on a wire rack set over a tray rather than on kitchen paper, which traps steam and softens the underside you worked so hard for. While they are still hot, scatter over extra toasted sesame seeds and a small pinch of flaky salt.

To Serve: Honey, Ice Cream, and a Little Salt

Serve them warm rather than blazing hot — two minutes out of the oil is perfect. A generous drizzle of runny honey is the classic British instinct and it works beautifully, especially with a scoop of coconut or vanilla ice cream alongside so the cold meets the crisp. A squeeze of lime and a little finely grated zest cuts through the sweetness.

For something closer to the Thai original, skip the ice cream and serve them with freshly grated coconut, or a small bowl of palm sugar syrup. A pinch of salt on top is not a mistake: it makes the banana taste more of itself.

Small Tweaks Worth Knowing

• Batter too thick? Add cold water a tablespoon at a time. Too thin? A spoonful more rice flour.
• Fritters greasy? The oil was too cool. Let it come back to temperature between batches.
• Rewarming: five minutes in a 200°C oven restores the crunch. Never use a microwave — you will get rubber.
• Make ahead: the dry ingredients can be mixed days in advance; just add the liquid at the last moment.
• Variations: a teaspoon of desiccated coconut or a grating of lime zest in the batter is lovely, as is a pinch of cinnamon in the sesame sprinkle.

Once you have made these a couple of times, the whole thing becomes instinct — a bowl of batter, a pan of oil, a pile of golden fritters on a rack, and a queue of people waiting. That is exactly how it should be.
