Short answer
Start the oats in cold liquid rather than hot, use roughly a 1:3 ratio of oats to liquid, and salt it. Adding oats to boiling liquid is what makes lumps.
Porridge is oats releasing starch into liquid, and how that happens decides everything. Started cold and stirred, it becomes creamy; dropped into boiling water, it clumps before the middles have softened.
What you'll need
- Porridge oats
- Water, milk or a mixture
- Salt
- Heavy pan (optional)
Step by step
- Start in cold liquid.Oats and liquid in the pan together, then heat. Adding oats to boiling liquid gelatinises the outside instantly and traps dry oats inside — that is what a lump is.
- Use roughly one part oats to three parts liquid.By volume, adjusted to taste. Less liquid gives a thicker result; more gives a looser one. It thickens as it cooks and again as it stands.
- Choose the liquid deliberately.Water gives a cleaner oat flavour, milk gives richness, half and half is a good default. All milk catches more easily on the base.
- Salt it.A proper pinch, at the start. Unsalted porridge tastes of nothing regardless of what you put on top — this is the most commonly skipped step.
- Stir regularly over a moderate heat.Not constantly, but often, reaching the base and corners. Stirring releases the starch that makes it creamy.
- Cook for four or five minutes for rolled oats.Longer for steel-cut or pinhead, which take 20-30 minutes and give a much nuttier texture.
- Take it off slightly looser than you want.It thickens in the bowl within a minute. Porridge that looked right in the pan is often stodgy by the time it is eaten.
- Add sweetness and toppings at the end.Sugar added early can make it catch. Fruit, honey, nuts and cream go on afterwards.
Tips
- Soaking oats overnight cuts the cooking time considerably and gives a creamier result.
- A heavy-based pan makes a real difference. Thin pans catch on the base and the burnt taste spreads through everything.
- For a single portion, a bowl in the microwave works well — use a bowl much larger than you think, because it boils over readily.
If it doesn't work
Lumpy
Cause: Oats added to hot liquid — Fix: Start them in cold liquid. A whisk breaks up lumps in an existing pan.
Claggy and stodgy
Cause: Too little liquid, or left standing — Fix: Loosen with a splash of milk or water and stir. Take it off the heat looser next time.
Tastes of nothing
Cause: No salt — Fix: Salt at the start. It is what makes the oats taste of oats.
Catches on the base
Cause: Heat too high, or all milk — Fix: Lower heat, stir more often, and use a heavy pan or part water.
Questions people ask
What is the right ratio for porridge?
About one part oats to three parts liquid by volume, adjusted to taste. It thickens as it cooks and again as it stands.
Should porridge have salt in it?
Yes, a proper pinch at the start. It is the difference between porridge that tastes of oats and porridge that tastes of nothing.
