For pressure cooking, if you aren’t following a trusted recipe, pay attention to minimum liquid requirements and maximum fill lines as indicated on the inner pot. For non-pressure cooking, the minimum liquid requirements listed below do not apply.

Minimum When pressure cooking, always add at least 1.5 – 2.5 cups (355 – 473 ml) of liquids so enough steam can be generated to cook under pressure. These liquids should be water-based, including stock, broth, juice, cooking sauces, as well as wine and beer. If a recipe specifies a certain amount, always follow the recipe. Note: Oils and oil-based sauces do not have enough water content to account for the required liquid volume.

Maximum When pressure cooking, do not fill the inner pot higher than the 2/3 line indicated on the inner pot. When cooking foods that expand (e.g., rice, beans, pasta) do not fill the inner pot higher than the 1/2 line indicated on the inner pot. Overfilling the inner pot may risk clogging the steam release and developing excess pressure. This may cause leakage, personal injuries, or damage to the cooker.
