How to Cook Every Grain: Water Ratios, Times & Tips
Every grain has its own rules, its own water ratio, its own timing, and getting it wrong is the difference between fluffy and gluey, or chewy and undercooked. Pick a grain below for exact instructions, or scroll down for the full chart.
Pick Your Grain
Tap a grain to see its water ratio, cook time and method.
Organic Quinoa Grain
Gluten-free · ready in under 20 minutes
Rinse well to remove the natural bitter coating, add to the pan with water, cover and bring to a boil. Reduce the heat, leave the lid slightly ajar, and simmer until the grain turns translucent and the spiral germ separates.
Organic Buckwheat (Raw)
Gluten-free · naturally nutty
Add raw buckwheat groats to boiling water, cover and reduce to a simmer. It cooks quickly and can turn mushy if left too long, so check for tenderness from the 10-minute mark.
Organic Millet Grain
Gluten-free · mildly sweet
Toasting the dry grain in the pan for a couple of minutes before adding water brings out a deeper, nuttier flavour. Simmer covered, then rest off the heat for 10 minutes before fluffing with a fork.
Organic Pearl Barley
Contains gluten · chewy texture
No soaking needed, the pearling process removes the tough outer hull. Simmer uncovered or partially covered, and drain off any excess water once tender, it works well straight into soups and stews too.
Organic Rye Grain
Contains gluten · dense and hearty
Whole rye berries benefit from an overnight soak, which shortens cooking time and softens the bran. Simmer gently until tender but still pleasantly chewy, rye rarely turns fully soft.
Organic Spelt Grain
Contains gluten · subtly nutty
Like rye, whole spelt berries cook faster and more evenly after a soak of a few hours or overnight. Simmer until tender with a slight bite, then drain any water that hasn't absorbed.
Organic Jumbo Oats
Gluten-free option available · breakfast staple
Use milk, plant milk or water, or a mix. Simmer gently, stirring occasionally, for a creamy porridge. For a faster bowl, swap in Organic Porridge Oats, ready in around 4–5 minutes.
The Full Reference Chart
Everything above in one table, for when you just need the numbers.
| Grain | Water Ratio | Simmer Time | Soak First? |
|---|---|---|---|
| Quinoa | 1 : 2 | 15–20 min | No |
| Buckwheat | 1 : 2 | 10–15 min | No |
| Millet | 1 : 2.5 | 20 min | No |
| Pearl Barley | 1 : 3 | 25–30 min | No |
| Rye Grain | 1 : 3 | 45–60 min | Recommended |
| Spelt Grain | 1 : 3 | 40–50 min | Recommended |
| Jumbo Oats | 1 : 2 | 8–10 min | No |
| Porridge Oats | 1 : 2 | 4–5 min | No |
Ratios are a starting point, older grains, harder water and altitude can all shift things slightly, so keep an eye on the pan the first time you cook a new bag.
The One Grain That Breaks the Chart
Organic Popping Corn doesn't follow a water ratio at all. Add a thin layer of oil to a heavy pan over medium-high heat, add the kernels in a single layer, cover, and shake occasionally until the popping slows to a few seconds between pops. No water, no simmering, just heat and patience.
Getting the Best Result
Do This
- Rinse quinoa and millet before cooking to remove their natural bitter coating
- Toast grains dry in the pan for a minute or two before adding water, for deeper flavour
- Salt the water rather than the finished grain, it seasons more evenly
- Let grains rest off the heat, covered, for 5–10 minutes before fluffing
Avoid This
- Lifting the lid repeatedly, it lets steam escape and slows cooking
- Stirring too often, especially with barley and oats, it releases starch and turns the pot gluey
- Skipping the soak on rye and spelt if you're short on time, they'll take noticeably longer without it
- Cooking straight from the fridge or freezer, let grains come to room temperature first
Frequently Asked Questions
What's the general rule for grain to water ratios?
Most small, quick-cooking grains like quinoa, buckwheat and oats use roughly 1 part grain to 2 parts water. Larger or harder grains like pearl barley, rye and spelt need closer to 1 part grain to 3 parts water and a longer simmer.
Do I need to soak grains before cooking?
Not always. Quinoa, buckwheat, millet and pearl barley cook fine without soaking. Whole rye and spelt berries, however, cook faster and more evenly with an overnight soak, since their tough outer bran slows water absorption.
Why did my grains turn out mushy or gluey?
This is usually too much water, too much stirring, or overcooking. Stirring releases starch, which is what makes rice pudding creamy but makes most other grains gummy. Stick to the ratio, cover the pan, and resist the urge to stir.
Can I cook a big batch and store it for the week?
Yes, most cooked grains keep well in an airtight container in the fridge for four to five days, and freeze well for longer storage. Cool them fully before sealing to avoid trapping moisture.
The Bottom Line
Once you know the ratio and the timing, cooking grains stops being guesswork. Keep this chart handy, adjust slightly for your own pan and stove, and you'll get consistent, fluffy results every time.
