How much dry rice per person as a side?

The standard UK portion for rice as a side dish or accompaniment is 75g of dry rice per person. For a smaller side, 50g is sufficient. This applies to most rice types including white long grain and basmati.

How much does rice increase in weight when cooked?

White long grain rice approximately triples in weight when cooked (3x). Basmati increases by about 2.8x, brown rice by about 2.5x (it absorbs less water), and risotto rice by about 3.5x (it absorbs stock during the long cooking process).

How much water do I need to cook rice?

The water ratio varies by rice type. Basmati and sushi rice need about 1.5 parts water to 1 part rice by weight. White long grain needs about 1.8:1. Brown rice needs about 2.2:1. Risotto needs about 3:1 as stock is added gradually.

Do I need to adjust portions for risotto?

Yes, risotto is typically served as a main course and uses more rice per person (about 100g dry) because the rice is the main component rather than an accompaniment. The rice also absorbs much more liquid, making each portion heavier.

How do I measure rice without scales?

As a rough guide, 75g of dry rice is approximately one-third of a mug or about 4 level tablespoons. A standard UK teacup holds roughly 180-200g of dry rice when filled to the brim.
