How to Remove Seeds From Blackberries for Pies


Blackberries produce a bumper crop with very little care year after year. Besides the thorns--and there are thornless blackberries--the only downside to blackberries is the seeds--each berry has quite a few. For some people, that's just part of blackberries; for others, it's annoying and they want the seeds removed, especially for blackberry pie. Blackberries also make great jams, sauces and a glaze for meats and ribs.


Step 1

Wash berries and pick over, removing unripe berries, leaves and any dirt.

Step 2

Put berries in a blender and puree. Add water--1/4 to 1/2 cup--if necessary to get the berries going.

Step 3

Strain with a fine mesh strainer to remove seeds.

Step 4

Push the remaining berry puree through the strainer with the back of a spoon to get the last bits.

Step 5

Add 4 tbsp. of cornstarch and 1 1/4 cups of sugar to each 4 cups of blackberry puree for the pie filling.


Step 1

Add 1/4 cup of sugar to each cup of washed and cleaned berries. Mix well.

Step 2

Mash the berries slightly to release some juice.

Step 3

Let the berries sit at room temperature for an hour. The berries should become very juicy as the sugar draws out the juice. If there's not enough, add 1/2 cup of water to each cup of sugared blackberries.

Step 4

Cook over slow heat until berries come to a boil and start bursting.

Step 5

Sieve the berry mixture to remove the seeds.
