Even our old stovetop ones are failsafe. But it's good practice to look
at the steam vent to make sure there is no crud blocking it. Then:
1. Put food and liquid in cooker
2. Seal lid
3. Put regulator weight on steam vent
4. Put cooker on heat.

Some of the liquid boils and turns to steam, pushing up the pressure
indicator, and causing the regulator weight to rock. No rocking, vent
might be clogged. Vent clogged, pressure pushes out safety fuse: "POP!"

If still left unattended, the liquid will all boil away and the food
would scorch as in an ordinary pot. But no chance of hazardous pressure
building up.

Your mom must have forgotten some of the instructions that came with
the cooker. Blowing the weight only happens when the vent gets
blocked.

I've never cooked in a pressure cooker but I've canned a lot of veggies in my pressure canner. You could cook in it but it's pretty big.

Sounds like that's what nb's mom was using.

My canner is a Mirro 12 qt, it's the same size as a Presto 15 qt, the Mirro has a high domed lid. Either will can 7 qt jars or 10 pint jars. Some bigger ones can do 20 pint jars, some will even do 14 qt jars but they cost a lot, are hard to find and take much longer for pressure to build up and pressure to go down.

I have a pressure canner which is huge but for everyday use I have 2 Hi Dome
Prestige cookers which suits me fine.
