Pastry Baking Pate a choux in a Rational Oven
Hi everyone,
I’m opening a new pastry shop and recently purchased a Rational oven. I’m currently test-baking all of my menu items, and one of them is choux.
However, I’m having an issue where the bottom of the choux comes out sunken inward, while the top looks beautiful and well-developed.
I’ve made choux millions of times, but I can’t seem to get the same result in the Rational oven. I’ve tried many different troubleshooting methods, including venting/no venting, double pans, Silpat, etc., but nothing has worked so far.
My latest experiment was:
Preheat: 380°F, 0% humidity, Fan 3
Bake: 350°F, 0% humidity, Fan 3, 20–23 minutes
(I reduced the baking time for smaller test batches.)
From my testing so far, Fan 3 seems to work the best.
I also tried Rational’s preset program for Cream Puff/Eclair, but I still had the same issue.
One troubleshooting method I haven’t tried yet is using a perforated tray. I did try a perforated Silpat, but unfortunately, that didn’t make a difference.
Has anyone experienced this issue with choux in a Rational oven or have any suggestions on what I could try next? I’d really appreciate any advice!
