Why would you heat treat flour?

Raw flour is considered unsafe to eat due to the presence of potentially harmful microbes.

According to the FDA, the grains from which flour is ground are grown in fields that may be exposed to harmful bacteria like salmonella and E.coli.

Heating flour to at least 160 degrees kills off any nasty bacteria that might be lurking in your flour bag.

In most desserts, the dangerous microbes get killed during the baking process. But if you’ve ever found yourself nibbling raw cookie dough, you know that plenty of our favorite treats never see the inside of the oven door.

Taking a few minutes to heat treat (bake) raw flour makes it safe to use in all kinds of recipes. From no bake cookies to edible raw cookie dough!
