Cheesy Dip with Tomato Salsa

Chorizo first, dry pan, no need to add fat before it — a tablespoon of olive oil is there as insurance against sticking, not as the main fat. You want the edges catching colour and the oil in the pan going a deep orange-red, not just pink. That colour change is your doneness marker, not a clock. Onion goes in after, into that already-flavoured fat, and you're watching for it to go soft and translucent — a raw, stinging onion bite anywhere in the finished dip means it didn't get enough time here, not that you need more onion.

Cumin and garlic go into butter next, over a heat gentle enough that you can hold your hand near the pan without flinching — hot enough to toast the spice, not hot enough to scorch the garlic bitter. Burnt garlic is one of the few flavours you cannot cook your way back out of, so this is the one moment in the whole dish where "low and careful" actually matters more than anywhere else. The jalapeño brine you're told to add isn't an afterthought — it's acid and salt arriving early, seasoning the fat itself rather than just the final dish.

Milk and corn starch: mix them together before they meet heat, always, because starch dropped straight into hot milk clumps into little gluey balls that never fully dissolve — that's a kitchen myth in reverse, people think stirring harder fixes it, but by then it's structural, not a stirring problem. Whisked into cold or cool milk first, it disperses evenly and the sauce comes out smooth. Bring it up slowly — a "gentle simmer," meaning small bubbles breaking at the edge of the pan, not a rolling boil — because starch needs sustained gentle heat to actually thicken, and a hard boil will break it down again almost as fast as it set.

The cheese goes in off a slightly reduced heat, cut small so it melts evenly rather than sitting in the middle as a hot core surrounded by melted cheese at the edges — size here is about surface area, not neatness. Any firm, well-aged cheese with good melt and real flavour will do this job; mature cheddar earns its place because it's sharp enough to stand up to chorizo fat and lime, where a mild cheese would just disappear into blandness. A Comté or a good Gruyère does the same mechanical job if that's what's in the fridge, though the flavour note shifts nuttier and the dish stops being quite so British-Tex-Mex.

For the pico de gallo, chop the tomato finely enough that each spoonful carries all the components, and don't salt it until close to serving — salt pulls water out of tomato and onion by osmosis, and that water is exactly what turns your crisp salsa into a watery one sitting under the chips. Splitting the chilli, half in early and half added at the end, is a real technique, not fussiness: the early half mellows and spreads its heat through the whole bowl as it sits, the late half keeps its raw bite, so you get background warmth and a sharper top note in the same mouthful.

Any neutral oil with no smell of its own — sunflower, a mild rapeseed — stands in for olive oil in the salsa if you want the lime and coriander to carry the dressing unchallenged; olive oil's own flavour is fine here but not essential the way it is in the pan with the chorizo, where it's mostly there to stop sticking rather than to taste of anything. This isn't a dish that rewards rushing at any stage — the starch needs its slow simmer, the garlic needs patience in the butter, the tomato needs to sit untouched by salt until the end — and the fifteen minutes of prep on the card undersells how much of this is about waiting for the right visual cue rather than watching a timer. Four people, a bowl of chips between them, lime wedges on the side: it's built for sharing straight from the dish, not for plating up neatly.
