I took them out and sat them upright, sealed the ziplock seal as far along as I could, then laid the bag gently flat to finish getting the air out. I did seal some directly in the pot. I think too much air would be a problem (it expands), but a little is ok.
Any safe, airtight bag (and bag sealing method) and any gentle heat method would be ok.
Yes thats the bag Im talking about. Ok if your thinking about them I am too lol. Yes better then a zip lock i think and I dont need the container. just put them in the water. Should we seal them? Or do they need to breathe a little?
Redhead, I found that the seal (of the bags I use) need to be kept out of the water, otherwise they fail (small sample rate, but about 30% seam failure, or bag opening, when the seal is wet from either being in boiling water or being turned upside down).
Your bags sound like they were made for being put into boiling water, so perfect!
The bag needs to be kept airtight for the entire cook.

I often seal soup stock in my vacuum seal bags. Yes, it's tricky. Stock leaks while the vacuum seal is sucking air out of the bag, so I wouldn't squeeze all the air out with active lye in the batter. If you can hold your bag below the level of the counter where your sealer sits, that can help prevent too much spillage.
I agree, if you can get most of the air out, without laying it flat, then do that (I did it initially to take photo's).
[I haven't tried vacuum sealing soap batter, and I won't. I'd end up hurting myself and making a mess!]

I also had a bag-melting event, when I clipped the bags to a metal skewer ... the skewer transferred heat.
When I steam them, I put them directly into the bamboo steamer, the steam needs to be very gentle.
The jug was to ensure no mess from bag failure (which has not been needed, except for the above noted seal immersions) and to ensure gentle heat (which could be controlled in other ways).
I have found the suis-vide temperature needs to be well below a simmer when placed directly in the water or steam environment, as high, rapid heat causes bubbles in the soap.
