Yes, slice and fill the croissants, then place in an airtight container (or on a well-covered tray). Make the honey mustard glaze up and then cover and refrigerate that too.Take the glaze out of the fridge about 1 hour before you want to cook the croissants - so it can come up to room temperature.Transfer the croissants to a tray, then brush with the glaze and sprinkle on the poppy seeds. Cook for 6-7 minutes at 190C/375F.You can also make the whole croissants ahead and cook them. Then cool, cover and refrigerate. They're a little dryer this way, and the glaze won't be as sticky, but they're still delicious. Reheat by placing in the oven for 5 minutes at 190C/375F - until piping hot throughout.Or you can reheat in the microwave for 1-2 minutes until piping hot throughout. However, microwaving them means the croissants won't be as crisp on the outside.Nutritional information is based on one serving.
