Pressure Cooker - 6 qt or 8 qt? - Cookware - Pressure ...- how can i make soap bar at home ,When can you not make small quantities in a larger cooker? And for a number of ingredient types, you can only fill the cooker half full rather than 2/3, because the foaming of some ingredients would otherwise foul the valve. All that said, I do gather that a 6 quart size can be fine, and testimonials like yours bear that out.Storing French Macaron Shells - Home Cooking - Macarons ...I am hoping to make the shells a few days before that, though. How far in advance can you make macaron shells and what is the best way to store them? I have read that they can be frozen but I am wondering if I can just keep them in the fridge since I will be using them a day or two after I make them. Thanks.
