For a standard, satisfying single serving of porridge, the ideal measurement is 50 grams of rolled oats (or 40 grams if you prefer a lighter portion).
When it comes to the liquid ratio, you will want a 1:5 weight ratio (or roughly 1:2.5 by volume). For 50 grams of oats, measure out 250 grams (or 250 milliliters) of liquid. You can use whole milk, water, plant-based milk, or a 50/50 mix of water and milk depending on how rich and creamy you like your porridge. Be sure to add a small pinch of fine salt, as it brings out the natural sweetness of the grain.
For the cooking time on a stovetop, combine the oats and liquid in a small saucepan over medium heat. Bring the mixture to a gentle boil, then lower the heat to a gentle simmer. Cook for 4 to 5 minutes, stirring continuously with a spoon or spatula to release the starches and create a smooth texture. Once thickened, remove from heat and let it rest in the pan for 1 minute before serving so it finishes setting to the perfect consistency.
