Notes about this recipe

Great concept, i changed a few things out of necessity and haste - ran out of dijon so used half and half dijon & whole grain mustard. Very good ?? - we don’t eat pork so i used beef pastrami. Very good ?? - used a combination of mozzarella and Irish blue brie cheese. Very satisfying , goey but salty and stinky at the same time. - topped it with feta instead of cheddar. Worked well ?? - i didn’t have time to wait for it to soak up the custard so i had to rely on brute force and ingenuity. Covered the pyrex in cling film and pressured the sandwiches into soaking up their share of egg. Then proceeded to the oven at 150 fan covered with foil the entire time. Removed the foil once it was done and pop it under a griddle to crisp it up. It worked a treat. It was oozing it was moist it was stinky and it was crispy on the top. Fed 2 greedy adults and an equally greedy toddler. Served it with a gherkin and mustard relish (shop bought). It needs something sharp and vinegary to cut through all that cheese. I happen to have this one to hand but cheese + gherkin + mustard is a 10/10 combo ??

I made this recipe for breakfast yesterday and didn't find it dry at all. It was super tasty and I loved the fact that all you need to do in the morning is take it out of the fridge and pop it in the oven. I did let it soak overnight, and used the remainder of a dense loaf of grainy pane di casa that was starting to stale. I also lowered the oven temperature to 180 degrees because I have a fan-forced oven, rather than using the 200 degrees listed in the recipe. I'll have to try Nadiya Hussain's Savoury French Toast to compare!

This was OK, but a little on the dry side - don't know if I should have soaked it all for longer (I only left it for an hour as opposed to overnight) or reduced the heat/time in the oven a bit. Aside from that, every breakfast recipe along these lines is, for me, competing with the ultimate toasted breakfast sandwich recipe of all time, which is Savoury French Toast from Nadiya Hussain's Time To Eat, and this one failed to live up to that standard in every way.
