Instead, you can use any sealable bag for sous vide, as long as you previously check that it won’t melt or deform in very hot water. Here’s how to eliminate air from a bag without the assistance of a vacuum.

Quick Tip





I just tried the Champagne Zabaglione recipe, and it was quite thin. When I tried to fold it into soft-peak whipped cream, the result was foamy liquid. I’m guessing I should have cooked longer than 20 minutes?
Hmmm. Well, zabaglione, when served warm, is somewhat thin; you can probably see that from the photos that accompany the recipe http://svkitchen.com/?p=3467 . But it sounds like you folded the warm zabaglione into the whipped cream, and in that treatment it needs to be chilled first. Suspect that’s the issue and not the cooking time. Sorry for the delay in responding — we all were out of town for the long Thanksgiving weekend!
No, the zabaglione was definitely at refrigerator temperature, as was the whipped cream. I made another batch and started checking the consistency every 10 minutes starting at 20 minutes. It was watery at 20. It finally looked like the photo (about like hollandaise) after 1 hour. I also whipped the cream to stiff peaks instead of soft peaks (I know what these terms mean– really). This time it was perfect. I am mystified by the discrepancy in our results. Your recipe says 165 degrees F; is that correct?
Boy, this is a head-scratcher, Harvey. We’ve done this recipe several times without issue, and it’s also appeared on both the SousVide Supreme site and Cooking Sous Vide. First time we’ve gotten this feedback. I’m so sorry; not sure what to suggest. The temp is definitely 165°F. Have you ever checked the temp of your water bath with an instant-read thermometer? Grasping at straws here. Can’t promise it this week, but we’ll try it yet again and let you know if the results are different. Keep us posted, too, if you have any insights.
