I have never made a recipe that called for sifted flour ....so obviously, I know very little about sifters. One of my customers just placed an order & said that she needed a flour sifter & wondered if PC had one. I see that the Strainer can also be used as a sifter, but how does it work? The sifters that I have seen before all have a handle that you turn or pump the flour through, so I'm curious about the Strainer and how it can double as a sifter. Sorry if this is a silly question, but I don't want to suggest a product that won't meet her needs. I know my fellow cheffers can help!
