One note I'd make, though, is that US, UK and Australian cups are all different sizes. (and possibly others?)
And from the one recipe I saw it looks like you're using UK cups? But, possibly not as well... Either way, it might be worth calling that out, or allowing for cup-type specification similar to how you do for weights?
Somewhat related, some sites call out egg weights too, and that might be something to try and do here too? (Because, if nothing else, egg weights are often written on the carton which acts as a guide; even if people don't actually weigh them.)
Another thought, again... Some kind of showcasing? A la Github's explore, or even "awesome" pages? I might be off, but to me discovery is really important for recipes and I love browsing "cookies" or "desserts in a hurry" or similar; and pages akin to that with community curation could be nice?
Hmm, another random idea... Some kind of more granular forking to facilitate things like "do you have a stand mixer?" and that kind of distinction? (Coupled with "equipment switches" maybe?) In the past I've done recipes that required something I didn't have, and I've had to tweak fairly aggressively to make it work, but when/if it did work, maybe adding that feedback into the recipe would be valuable? e.g. user ticks "don't have a dehydrator", and recipe tweaks to "use your oven and set it low", etc.
Anyway... It looks awesome! Keep doing what you're doing, and I'll use it :-) Just some random thoughts that came to mind :-)
