Canning them in apple juice or peach juice works good. My pears don’t juice they slurry. Years ago I thought I would make some pear cider but I found out pears don’t juice. My mom came to my rescue and made my mess into pear nectar. She added water which was odd to me. It’s how I learned to make pear sauce because i found out by blending the pear up i got pear sauce in the blender. Cooked the pears down and canned the sauce. Fought to try and get that juice but those pears were not have having it. Apples are easy to juice. Peaches I steam juiced then canned blackberries and pears in the juice.
