Hi guys. Im trying to create a pastry cream with swirls of jam. Anyone with good tips how to accomplish this? The goal is to have pastry cream and in it are swirls of jams (either 1 or multiple flavors) that should be distinguishable from each other. There would be some level of mixing but i am hoping theres a way to keep them separate even after piping into an eclair so that when someone bites into the eclair the person can see and taste the different flavors.
