The starch takes up most of the plate, absorbs most of the sauce, and receives almost none of the attention. It is also where a surprising share of disappointing meals actually go wrong: a good curry over gluey rice is a disappointing dinner, and no amount of care in the curry fixes it.

None of this is difficult. It is mostly a matter of a few ratios, salting at the right moment, and understanding that starches keep cooking after you take them off the heat.

Pasta: the water, the salt, and the water again

Pasta needs a large volume of well-salted boiling water, and the salt matters more than any other variable. It is the only opportunity to season the pasta itself; salt added afterwards sits on the surface. Aim for water that tastes clearly salty rather than faintly of the sea.

The second thing worth changing is what happens after draining. Pasta finished in the pan with its sauce and a ladle of starchy cooking water emulsifies into something that clings. Pasta drained, plated, and topped with sauce is two separate foods sharing a bowl.

• Do not add oil to the water. It coats the pasta and stops sauce adhering, and it does not prevent sticking — stirring does.
• Reserve a mug of cooking water before draining, every time. The dissolved starch is what thickens and binds the sauce.
• Undercook by a minute, then finish in the sauce for that minute.
• Rinse only if the pasta is going into a cold salad.

Long grain rice: rinse, ratio, rest

Gluey rice is almost always excess surface starch, too much water, or stirring. Rinsing until the water runs mostly clear removes the loose starch that otherwise turns the outside of each grain into paste. Two or three changes of water is usually enough.

Then the ratio. Most long grain rice cooks well at roughly one part rice to one and a half parts water by volume, which is less than the two-to-one that packets often suggest. Bring it to a boil, cover, drop to the lowest heat for around twelve minutes, then take it off and leave it covered for ten more.

• Do not stir rice while it cooks. Stirring breaks grains and releases starch — that is how risotto is made, and it is the opposite of what you want here.
• Do not lift the lid to check. The steam trapped under it is doing the cooking.
• The rest off the heat is not optional. It lets moisture equalise so the bottom is not wet and the top dry.
• Fluff with a fork, never a spoon.

The other rices behave differently

Rice is not one ingredient. The variety determines both the method and what the finished dish can be, and using the wrong one is the reason a dish sometimes fails despite perfect technique.

• Basmati and jasmine: rinse, low water, rest. Aromatic, separate grains.
• Short grain and sushi rice: rinse thoroughly, slightly more water, sticky by design.
• Risotto rice (arborio, carnaroli): do not rinse. The surface starch is the sauce, and stirring is the technique.
• Paella rice (bomba): do not rinse and do not stir. The bottom crust is the point.
• Brown rice: longer, more water, and best treated almost like pasta — boil in plenty of water, then drain.

Grains: treat most of them like pasta

For quinoa, farro, pearl barley, freekeh, and bulgur, the simplest reliable method is to boil them in a large volume of salted water and drain when tender, rather than trying to hit an exact absorption ratio. It is far more forgiving and works across brands that cook at different rates.

Quinoa is worth rinsing regardless of what the packet says; the natural coating on the seeds is bitter, and rinsing is the difference between nutty and soapy. Couscous is the exception to everything above — it is a pasta, not a grain, and needs only equal-volume boiling liquid, a lid, and five minutes.

Season the starch itself

This is the single change that improves the largest number of meals. Salt the cooking water for anything boiled, and consider cooking the starch in something other than water when the dish allows: stock, coconut milk diluted with water, or water with a bay leaf and a smashed garlic clove.

Finishing matters too. A knob of butter or a spoonful of oil stirred through rice or grains off the heat, plus a little acid or fresh herb, turns a neutral filler into part of the dish.

Cooling, storing, and reheating

Cooked starches are among the more fragile things in the fridge, and cooked rice is the one that deserves genuine care. Cool it quickly by spreading it out rather than leaving it in the pot, refrigerate it promptly, keep it no more than a day, and reheat it until steaming hot throughout.

Pasta and grains keep three or four days and reheat best with a splash of water in a covered pan. Cold cooked grains are also excellent as the base of a salad, which is a better use of leftovers than reheating them into something soft.

Portions, honestly

Dry weights per person, which are more reliable than volume and stop the routine problem of cooking twice what anyone eats: roughly 75 to 100g of dry pasta, 60 to 75g of dry rice, 60 to 75g of dry grains.

Serving sizes on recipe cards, including on this site, are approximations rather than measurements. If a recipe says it serves four and the ingredient list looks thin for four, trust the ingredient list.
