Yes.
Yes you can make frosting in salted butter
Makes the butter to make butter icing more firm (so you are able to put it into a piping bag and decorate.) Also makes the butter icing taste sweet ^^, xx source: me, currently taking food technology in GCSE (: hope it helps, LOL sorry if it's a short answer and sorry if it's not detailed and very good. >.<
in fact yes sometimes i take the icing off cupcakes tast real good without frosting or icing.
Cream-Well also known as 'Cream Mixture' is an ingredient that has similar texture like the vege shortening. It helps to regulate the butter cream taste and texture. Without 'cream mixture' our butter cream will be too oily and buttery then both kids and adults will not really enjoy the after taste after taking too many cupcakes or cake with butter cream.
icing sugar in a bowl then a bit of butter - a teaspoon or less and then a small amount of cocoa - a tablespoon? depends on how much icing sugar you use but just make it to taste. then boiling water and mix until it is the right thickness for you.
The butter in buttercreme icing is just used as a flavor additive. I would be careful using margarine that may have a different taste. I would advise using a butter-flavored margarine if you decide to make the substitution.
Without a doubt. Always use butter
No. It may kill any bacteria, but the butter will still smell and taste rancid.
This is purely a question of opinion and personal taste, some people may prefer peanut butter with jam, and others without.
yes, it taste good.
Yes, you can substitute lard for vegetable shortening in buttercream icing, but it will affect the texture and flavor. Lard has a distinct taste that may not be as neutral as shortening, which could alter the overall flavor of the icing. Additionally, lard may make the icing softer, so you might need to adjust the amount of powdered sugar or refrigerate the icing for better consistency.
yes it does
