Description
Emulsification of olive oil and walnuts to create a rich and creamy walnut sauce.
Technical
This technique involves slowly adding olive oil to a mixture of walnuts, garlic, and lemon juice 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 oil addition rate. The optimal temperature for this process is between 15°C to 20°C.
Culinary Significance
