Start folding gently forming a letter J with a spatula until the batter reaches the proper consistency.
Beat the softened cream cheese and butter together in the bowl of an electric mixer, for about 2 minutes, until light and fluffy.
Prepare the macarons and lay them on a tray, so you can paint on the shells.
Egg white powder: Egg White Powder is not the same as meringue powder. Egg White Powder is made of only egg whites. They help with getting fuller shells, and specially when adding a lot of food coloring to the batter, because they make the shells dry faster. I recommend experimenting with it if you can find it. I use 4 grams for each 100 grams of egg whites.
Vinegar: Before starting make sure to wipe down the bowls, whisks, silicone mats and everything you are going to use with vinegar, to avoid any grease particles of coming into contact with the meringue and batter.
Macaron amount: it will vary greatly depending on how big you pipe the shells, and on how runny or thick the batter is.
Baking time/temperature: Baking time and temperature will vary according to your own oven. I recommend experimenting with your oven to find out the best time, temperature, position of the baking tray.
Oven thermometer: Make sure to have an oven thermometer to bake macarons. It’s one of the most important things about making macarons. Home ovens aren’t accurate at all at telling the temperature, and even a slight 5 degree difference can make or break your whole batch.
Tray rotation: Lots of bakers don’t have to rotate the trays 180 degrees in the oven every 5 minutes, but I do have to with my oven, or I will get lopsided macarons. Please adjust this according to your oven.
