As I'm standing there in the kitchen making my ice cream mixes today I got to thinking...

Have you tried using canned pears? or are you using fresh pears and/or just juice.

Maybe trying canned pears in their own juice or in heavy syrup and pureeing them might give you a stronger pear flavor.

I found using the heavy syrup gives more flavor to the pear bread than using in their own juice ones.

Just a thought.
