Hi Annemarie, although we haven’t tested it, we’d start with the plant-based butter as a substitute. Let us know how it goes for you!

Hi Mysty, thank you. Some ingredients do weigh 250g per U.S. cup, but some do not. Ingredients weigh different amounts. For example, 1 U.S. cup of chopped nuts weighs less than 1 U.S. cup of sugar. 1 cup of spooned and leveled flour (125g) weighs less than 1 cup of peanut butter (250g). Hope this helps.

So glad to read this! Thank you Heather.

I believe the rising of the crust from underneath the pecan mixture might be caused by the application of butter on the crust. It probably made it too soggy. I bake lots of pies and don’t butter the crust before baking.

Hi Martha, 2 teaspoons of cornstarch work as a substitute for 1 Tablespoon of flour. Make sure the cornstarch is completely mixed in with the melted butter and brown sugar. Be sure to also check the packaging, as some cornstarch brands may not be considered gluten free if made in a factory with other gluten products.
