Money is SUPER tight for us this right now and we ran out of milk and couldn't go get more. I found a box of coconut milk in the pantry and looked up recipes for coconut milk bread.
Turns out that there is a Samoan Coconut Bread called Pani Popo that fit the bill perfectly. A very easy dough to make that is forgiving and very tasty.
The slightly sweet bread is a great pairing for the pork shoulder that I cooked sous vide for 36 hours.
I used this recipe: https://youtu.be/Tkx4lNpX3N4?si=D8ysm_BgWRsvw7JF
Why are you being so needlessly judgy? Maybe they have more money coming that will allow them to comfortably pay the electric bill by the time it comes. Maybe they wanted a special meal and buying & slow cooking the pork is how they budgeted their money. We have no idea about OP's circumstances and frankly, it sucks that you felt the need to comment on how they're doing everything wrong. They were excited about their ingenuity in the face of difficult circumstances and just trying to share something they were proud of with the community.
(Btw, I was curious so I did some googling and using this guy's sample numbers, a 36 hr cook would use around $0.60usd in electricity. So changing cooking methods is not really an effective way here to save money.)
