Yes—avocado freezing is safe when done as a purée. Whole or sliced avocados tend to go mushy and waterlogged, so blitz the flesh with lemon/lime juice and freeze airtight at 0°F / -18°C. Expect texture changes after thawing; ideal for guac, smoothies, dressings, and baking.

Yes — watermelon freezing works, with a caveat. Freeze seedless cubes or purée for smoothies, slushies, granita, and cocktails; expect softer texture after thawing. Keep cut melon at ≤40°F/4°C and freeze at 0°F/−18°C. Quality is best within months; safety at 0°F/−18°C continues indefinitely.
