Yes, but to get that filling inside can be tricky sometimes. While a pastry bag is often used to insert filling into baked goods, this can sometimes be too wide. A meat injector provides value in this situation because it is so much smaller. The hole is a lot less noticeable and the filling will stay inside the baked item, rather than seep out. Eclairs and puff pastries are just some of the delicious goods that you can create with a meat injector.
