Summer Rolls with Vegetables and Halloumi

Halloumi: the brining is why it fries instead of melting into the pan — that firmness is the entire point of the cheese, and it's the reason it survived centuries as a travelling, keepable protein in hot climates with no fridge. Buy the block, not pre-sliced strips if you can avoid it — pre-cut dries at the edges before it ever sees oil. If you can't get halloumi, you want another salty, high-melting-point cheese — paneer is the honest substitute, same brining logic, same reason it holds a fry.

The oil for frying it needs to do one job only: carry heat to the cheese without adding its own flavour on top of soy, hoisin and ginger that are already busy. Sesame oil here is for its own taste, so use it, but if you don't have it, "any oil with no smell of its own" is the rule — sunflower, groundnut, a flavourless rapeseed. Olive oil fights the dish; it has an opinion.

The dip is where most people under-season without noticing, because peanut butter and coconut milk both taste "finished" on their own and mute everything you add after. Taste it only once it's fully mixed, never mid-stir — soy, lime and hoisin need a minute to actually distribute through a fat-heavy base, and judging it too early means you oversalt trying to fix a flavour that was never missing, just not yet spread through. If it seizes up thick as paste, that's not a mistake, that's what peanut butter does in contact with acid and salt — loosen it with more coconut milk, a spoon at a time, not water, or you dilute the flavour instead of just the texture.

Carrot and cucumber in strips, not grated — grated vegetables weep water into the roll and that water goes straight into the rice paper from the inside, turning a sheet that's already damp from dipping into something that disintegrates. Cut with a knife or a julienne peeler, something with a flat edge, so the strip has a cut face rather than a torn one — torn vegetable edges release juice faster.

Spinach and the herb bunches are there for a smell, not a crunch, so they go in loosely, not packed — a tight wad of basil in a roll just becomes one solid flavour note instead of something you taste in passing. Strawberries are the one unexpected ingredient on the list and they're doing what pickled or acidic fruit usually does in a dish like this: cutting the richness of peanut and coconut with something sharp and cold. If strawberries aren't in season or you can't find decent ones, a sharp fruit with real acid does the same job — a few slices of unripe mango, or even apple, though it won't carry the same scent.

On the "medium heat" question for the halloumi: there isn't one you can rely on here because every hob is different, so don't look for a number. Watch the oil — it should shimmer, not smoke, before the cheese goes in. Smoke means the outside will scorch before the middle's warmed through, and a scorched edge on halloumi doesn't crisp, it bitters.

And patience is genuinely the scarce ingredient in this one, more than any item on the list. Sixteen sheets of rice paper rolled one at a time, each needing its own dip, its own wait, its own careful fold — that's real time at the counter, not active cooking time, and the recipe's "45 min cook" undersells how much of this is standing there with wet hands. Rushing the roll is the single most common reason these fall apart on the plate rather than in the kitchen.
