Foods That Don't Freeze Dry Well Butter, oil, and fatty meat cuts don't freeze-dry well because fat doesn't sublimate like water. These foods can go rancid over time. Syrupy or sugary foods such as jam or honey don't freeze well, as their high sugar content prevents proper sublimation. Drinks like soda won't freeze-dry effectively because of the carbonation and high liquid content.
