I have a question about step 3 on the recipe "Boston Cream Pie with Kahlua ganache" from sdebrango. It says: Hi. It looks really good, but my custard turned out dry/rubbery, not sure why, it started to look like scramled eggs in the pan. could you tell me what mistake that I may have made. I put some of the frosting on the dry custard, am crossing my fingers, LOL.
"Transfer to bowl. Add vanilla extract now if you did not use a vanilla bean and add the butter stir and cover with plastic wrap pressing it directly onto the surface of the cream. Refrigerate until completely cooled."
