Would a cake with this filling be able to sit out for several hours? I've heard if the sugar ratio is high enough, it is fine.
What is/where can you buy Polander seedless raspberry? Is it a jar of Jam? Also could this be used as a frosting/topping instead of a filling? Sounds delicious, can't wait to try it out!
You can find the Polander jam down the jelly aisle at Meijer
