During the first step, you should refrigerate the walnuts for approximately thirty minutes before using them in the recipe. Although this Chile Relleno White Sauce recipe calls for finely chopped walnuts, as long as the walnuts are deshelled, it will do.
In a food processor, process the dry ingredients and walnuts together. Although it is tempting to add the wet ingredients like half and half, this can actually make it harder for the dry ingredients to break down.
For a smooth texture, be sure to process them properly. This step should only take about 30 seconds but may take longer as all food processors are different.
Once the dry ingredients are processed and thin, you can then add the wet ingredients, not including the pomegranate seeds. In this Chile Relleno White Sauce Recipe, the pomegranate seeds go on top as a garnish. The texture should be thick. Most of the time, the sauce is served cool.
