Bake on the center rack for 13 - 16 minutes. (Bake them for 13 minutes for moist and fluffy centers as in the photo to your right. The crust will be soft. For completely hallow centers and thin crisp shells, after 10 minutes, lower the heat to 350 and bake an additional 9 minutes.) Just take one out of the oven and test it after 13 minutes. When it meets your desires, remove them all from the oven.
Guar Gum:
When making the dairy free version using guar gum, you will need to add an additional 1-1/2 teaspoons more guar gum to the 1/2 cup of all-purpose flour blend. If making the dairy version using guar gum, I suggest adding 1-1/2 teaspoons additional guar gum to the entire batch of all-purpose flour blend, that's about 1/3 teaspoon per cup of flour.
Variation:
Melt good-quality chocolate and dip the tops of cooled chouquettes in the chocolate; set aside to until the chocolate sets.
