Korean baby porridge: the 1:10 ratio

Korean recipes describe baby porridge by a number: 10-times porridge means 1 part grain to 10 parts water. The number drops as your baby grows, until it's soft rice.

The ratio by stage

RatioWhenTexture
1 : 10First days (around 6 months)Pours off a tilted spoon
1 : 8 – 1 : 9From week 2–3Drips, then breaks off
1 : 6 – 1 : 8Two meals a daySits on the spoon, a little grainy
1 : 4 – 1 : 6Around 9–11 monthsSoft, grains visible
1 : 2 – 1 : 4From 12 monthsVery soft rice

Your baby sets the pace, not the calendar. If they swallow easily and don't hold food in their mouth, go one step thicker. If they gag or keep spitting out, go back a step for a few days.

Water or vegetable stock? From two meals a day, we cooked the porridge with unsalted vegetable stock instead of plain water. Plain water is completely fine. If you use stock, pick one labelled "no salt added" ("low sodium" still contains salt), and skip stock cubes or bouillon, which are too salty for babies (NHS).

How to make it

  1. Whisk 10 g oat flour (or plain rice flour, not glutinous) into 100 ml cold water.
  2. Simmer on low, stirring, 5–7 minutes until smooth and cooked through.
  3. Spoon test: it should pour off a tilted spoon. Cool, then portion.
  4. Fridge: use within 2 days (cooked rice within 24 hours). Or freeze in cubes and reheat once until steaming, then cool.

Why oats as well as rice?

Korean babies traditionally start on rice. US pediatric guidance says rice shouldn't be the only grain, because rice absorbs more arsenic than other crops. Using the same ratio, oat flour works the same way, so rotate the two.
