Tarte au Sucre Sans Gluten (Sugar Pie)

"This gluten free version of my family’s favorite French Canadian sugar pie is sinfully delicious...... Depending on the type of pie crust you use, you might not need all the sugar mixture. If you have any left, pour it in buttered ramekins (only fill halfway) and cook along with the pie. This goes well with a tall cold glass of milk.  ***Do not substitute the sweet white rice flour with regular white rice flour or you will have a gritty filling which is not very palatable.***"
