I melted Crisco and poured if into hot canning jars then put lids on them while hot. They seem to be holding up well. I plan to open a jar in a month or two and make some oatmeal raisin cookies. Then I’ll know more.
Using crisco, or any other artificial fat is extremely hazardous to your health. Margarine is even worse.
Those oils are a guarantee of getting type 2 diabetes. They cause your cell membranes to become impervious to water, thus not allowing water soluable nutrients in, leaving them stranded in your blood, to be later stored as fat.
