Wow! I have come full circle on this! Since DH doesn't care for leftovers at all I have been utilizing these for beans etc. I did have some burnt contents when for some reason I didn't lower the heat on the burner enough..And of course add a pat of butter or splash of oil to keep bean fRoth fROm plugging the jiggle mechanism.
.As far as icreasing the heat enough to use the 8 tealights, it looked like their would have been enough space (barely ) to balance some more tea lights
atop. I dont' know how this will work out when saved but say you have four tealights in a cross pattern couldn't you balance another tea candle at the intersEctions?
X3 X4 So balance the new teacandlE atop the inner edges of all 4 Xs?
