Smartwhip Pressure Table
Know exactly which pressure to use for the best results of any dish, infusion or drink
Getting the pressure right is essential for achieving the desired texture and intensity of any dish, infusion or drink. The Smartwhip pressure regulator allows you to do precisely this – tailor the pressure to achieve the perfect consistency every time. Learn to determine exactly how much pressure each creation needs by understanding the relation between foam density and pressure.
1. The Food Matrix
The food matrix considers the molecular relationship between the fats, proteins and sugars present in a recipe. Fat and protein are essential for stabilising a foam and ensuring the air bubbles remain intact. The higher the proportion of these components in the recipe, the more pressure is required to aerate them and achieve a stable foam structure.
2. The Siphon Contents
The amount of gas (in other words, pressure) required for each recipe is proportionate to the amount of free space in the siphon. The lower the contents, and the more free space there is in the chamber, the more nitrous oxide gas the recipe requires to fully penetrate the ingredients.
3. The Desired Level Of Aeration
As a general rule of thumb, the higher the pressure (in other words, the more gas you use), the firmer and more voluminous the resulting foam will be. It therefore depends on how voluminous and intense you want your recipe to become as the airier the foam is, the less concentrated the flavour is.
Foam pressure table
|Type of foam & level of foam density||Siphon contents||Recommended pressure (bar)|
|Soft and airy foam||300-450 ml||6-9|
|Thick foam||300-450 ml||9-11|
|Foam for cocktails||200-400 ml||8-11|
|Runny foam (e.g. soup)||300-450 ml||5-7|
|Firm foam (e.g. cakes & merengue)||200-250 ml||15-16|
