Baps...hello and welcome from another Indian...
Cheese spread...first off nothing similar to the Amul spread here. Below are pictures of fresh cheese spreads. When you open them, they appear fluffy unlike Amul. Some have specks of green and other colours in them, no worries just herbs, no fungus! The key words are: frisch=fresh, käse=chees, streichkäse=cheese spread, natur=natural (no herbs/spices), Naturfrischkäse is what you want I guess.
Or just order online:

And the closest thing to Britania cheese slices is M-Budget Scheibenschmelzkäse
. En guete!
