This recipe can quite easily be made using ordinary short crust pastry, but if you decide to follow the recipe and make gluten free pastry,,,firstly,, well done you,,,and secondly gluten free pastry is notoriously short and crumbly. Rather than rolling out the dough and trying to mould it into the flan tins you can easily line the tins using a patchwork effect with the pastry, as long as there are no gaps for the filling to seep through, no one will know. Most prepared English Mustards contain gluten, however, English mustard powder doesn’t. So if you have difficulty finding a gluten free mustard the powder is fine, just make up to required amount following manufacturer’s instructions… Failing that Dijon is just as delicious in this dish and gluten free.
