What You Need to Know
This technique involves heating the grapefruit juice and oil to a temperature of 80°C, then slowly cooling it while whisking, creating a stable emulsion through the formation of a complex network of lipids and proteins. The key variables are temperature, whisking speed, and cooling rate.
This technique is unique in that it uses a combination of grapefruit juice and oil to create a creamy and healthy sauce, commonly used in Italian desserts such as grapefruit gelato.
