I suggest buying in bulk then. These work well in fabric baggies

Or

Edit:

Also in case it’s not obvious. These aren’t magic. All they are doing is absorbing water and holding it until they are heated up again at which point they release it.

If you are drying them in the cabin you’re trying to reduce humidity in, and the oven vents to the inside of the cabin (more common in electric ovens, but I believe some lp ovens still vent some of the steam internally) you are keeping the humidity in a closed loop system. You need to dry these external to the system you’re trying to dry. (Be that an oven that vents outside or an oven outside of the cabin)

I suggest getting a weather station that shows humidity (can be had for $10-20) to see if you’re actually changing the humidity. Something like this
