I used to use a water bath and thought this was due diligence until I worked for a French-trained pastry chef who put me onto 80c no bath and no drama (as Cakeface posted.) A lot less hassle....have you ever flooded them while carrying?
With starch in it...that's Creme Patisserie
On the stovetop....that's Anglaise from a sabayon....a whisk has no place near a brulee
IMO the difference is a more grainy/less silky texture...I believe avoiding aerating your mix & then passing it, catches unwanted white before cooking avoiding this....
2 sprays of water speeds up the glazing or blitz up a hardened caramel to torch for a quick even result
