Frequently Asked Questions

Is 150g enough for 3 hungry adults?

Yes! 150g provides 50g per person (570 total calories), which with milk and toppings becomes a 250-300 calorie breakfast each. For very active adults, consider adding protein (nuts, yogurt) rather than more oats.

How much liquid for cooking 150g oats?

Use 600-750ml liquid (2.5-3 cups). For creamy: 1:4 ratio (600ml). For looser: 1:5 ratio (750ml). Steel-cut needs more: 900ml (1:6 ratio).

Can I prep 150g for the whole week?

150g covers 3 days optimally. For a full week (5 days), use 250g. Cooked oats last 5 days refrigerated, so Sunday prep works for Monday-Friday.
