I bought a new silicone mould this week, round rather than pyramid shaped like @Candy and @HAH have. It's so much better! I went for the tiniest ones, so each tray does over 400 treats, I'm using them for streaming at the moment. One chicken carcass, two eggs, some flour, made about 1,200! I seemed to get the batter just right this time too, nothing stuck.
How long do you leave yours to dry out? Mine were completely cold when I put them in the jar, but they've gone from quite crispy to soft now. Doesn't matter, as I'll have used them all up within a week, but wonder if they should be left In a cool oven to dry out longer?
Hooray, nice work @Natalie - they look great I haven’t made any of these ones for a while as I made a batch that went soft and then a bit mouldy in the jar. I need to experiment - the first batch were perfect, I think I left them in the oven a bit longer? Ideally I’m looking for biscuit texture rather than cookie softness, sounds similar to your plan. I’ll make some more and record my methods!
