You can also flavor the prunes by using a different soaking liquid. For example, soak the prunes in hot apple juice or hot tea.

If the prunes were very dry, they may need to soak longer.

This may take between 30 seconds and 1 minute, depending on how strong your blender is.

If you don’t want to spill the juice as you strain it, you can strain it into a large measuring jug or bowl before pouring it into a serving glass.

If you’d like your prune juice sweeter, stir in honey according to your taste. If you’ll be giving the juice to a baby under 12 months, avoid using honey because of the risk of botulism. You can store extra prune juice in an airtight container in the refrigerator for up to 1 week.

If you prefer, soak the prunes in hot tea or fruit juice.

The prunes will cool as they soak, so they won’t be hot at this point.

If you’re trying to relieve constipation, you could also use pear juice instead of prune or apple juice. For an even sweeter smoothie, blend in a ripe banana.

You may need to stop and scrape down the sides of the blender a few times.

If you like your smoothie extra cold, fill the serving glass with ice before you pour the smoothie into it.
