This applies to cheese sauces too. The recipe calls for 1 cup of cheddar. As much as I want to add 2 cups it will end up as spackle instead of cheese sauce so lets just use 1 cup.
Or making too much roux for the sauce. That’ll also cause it to come out as spackle instead of sauce.
The photo was done by Yann Le Poul who seems to be a Frenchman who photographs animals. You can see the photo credited to him by clicking on the photo and then a quick web search will bring up pages where he has won some awards for his animal photography.
That doesn’t seem safe to me since you’re basically pumping power back into the mains but no, I think most of the home battery backups systems have a switch that sits between the main and your house to control the flow of power in the event of a power outage.
They have whole house uninterruptible power supplies.
Uninterruptible power supply is what you want. It basically trickle charges a large battery and swaps to the battery when you lose power. They can last for a few hours depending on the size of the battery and the load on the circuit.
You can also use runny jam for syrup on pancakes. That’s what my grandmother would do with hers that “failed”. Blueberry pancakes with cranberry jam/syrup is amazing.
