My application is for juicing but I guess it would apply to fruit salads as well.
I have an auger-style crushing juicer and roughly remove seeds I see before ramming the orange/lemon/... pieces down the juicer chute. Unfortunately a few seeds escape detection and as I like to put the pulp back into the juice, I get a few crushed seeds in the juice. Not nice.
Are there any accepted utensils/techniques for removing the seeds beyond probing each piece?
