Generally, this does not make a huge impact on my every day life. I keep my sums for figuring out skirt proportions so I don't have to re-do the maths, I have lists of formulas I might need for various things so I don't have to figure them out. Most of my recipes require only simple doubling or halving if theres maths involved at all.
But this morning, I had no idea what I needed.
|As my husband pointed out, this looks like scrambled eggs. Believe me, its butter.|
A 500g package of butter costs between $2.69 and $3.15 depending on where I buy it. Cream costs $4.01 for 600ml. That alone tells me making butter is not cost effective, theres no way you can get 500g of butter from 600ml of cream, but I enjoy making butter, and was curious so see just how expensive it is**.
IF my maths is correct - and that is a big 'if' - it would cost me around $8 to make 500g of butter. Two-and-a-half to three times the cost of buying butter. Of course, this would also give me around 500ml of buttermilk, but I have no idea the value of buttermilk, as buttermilk in stores is cultured milk rather than the liquid left from making butter. We would use buttermilk - I would use it to replace water or milk in my baking - but its not something we would ever buy. Which leaves me with $8 butter. There are people who spend that much on butter - in fact I can easily find butter at the supermarket that costs more than that - but I'm not one of them.
I keep hoping my maths is wrong. This is a distinct possibility. But I've started on fresh paper 3 times so I would be less likely to contaminate my answers (this way I stare at my base numbers and panic for a while then try to figure out how to get to an answer instead of just putting the numbers into the same formulas and hoping my multiplication is correct - much more likely to be doing it right if I keep getting the same answer when starting from scratch), and keep arriving at the same amount. Fun as it is, making butter is not cost effective. Unless we develop a taste for buttermilk.
Gosh its fun though.
(Why was I making butter if its so darn expensive? We needed cream for dinner the other night. I only needed a small carton. They only had large cartons in the store. I decided I'd rather have fun making butter than go to a different store to get the correct amount of cream.)
*Yes, yes, Australians say 'maths' instead of 'math'. I have arguments with my husband about it all the time.
**Another thought, if manufacturers can afford to sell us butter at that cost, that is a huge markup on cream. HUGE.
