What points toward crispy, and what's proven
Fat and salt point the right way. They aren't proven yet.
Every popular tip gets checked against the same model,
and then against every other lever we tested on this dish at once.
Fat and salt clear the first test. Not the second.
More fat tracks with a
crisper edge in this dish's fitted model. That's a real pattern on
its own. Checked against the other 14 lever tests run on this same
dish, it stops clearing the bar for genuinely significant.
A directional signal, not a settled finding

A directional signal, not a settled finding
The one lever on this whole dish that holds up against every other one
we tested is leavening, on spread: more of it makes any gingerbread
flatter and wider, chewy or crispy alike. That's a spread lever, not a
texture one, so it doesn't answer "how do I make this crispier" even
though it's the cleanest result in the dataset. Fat and salt are the
closest things we have for that question. They just haven't earned the
same confidence yet.
We also checked one more thing and
came up empty: Whether egg firms or loosens the middle. Egg is one of the axes these recipes vary the most, and none of that variation lined up with a measurable change there, at any level of confidence. Reported here because "we looked and
found nothing" is a different, more useful claim than staying silent
about it.
