You could splash a bit of petrol on the bread lmao! Naa, simply making a small shrine to the Watcher and offering it on a plate is enough. Throw the bread out when it goes green and replace it. When in ritual, simply state that you have a sacrifice for it and push a plate with the bread on it out of your circle with your wand or a stick (make sure the stick is blassed or has protective seals/sigils on it just in case.) but make sure you yourself do not leave the circle as Watchers arnt very happy entities....
As for the 50 Names, I occasionally offer olives, bread and olive oil, fruit, I was once asked to offer rich soil (usually found in grave yards), sometimes they ask for favours, or you can make paintings of them, make effergies, clay models, you could even get a tattoo of their seal if you wanted lol. The is nothing written about sacrifice to the names of Marduk, so you don't technically have to give any. However, there is nothing stopping you from being creative, which is what magic is all about.
