Some of my hacks are:
My toilet bowl brush sits in a container. I add the last bit soap to the container, the last tiny sliver of the bar, shampoo, dish soap,. I add a bit of water if needed. Cleans the toilets just fine.
I premake "convenance" food.
Bread mixes - I make up the dry parts of recipes - biscuits, bread dough, pancake, cornbread etc. I label my jars with type and the needed wet ingredients. (I don't add the yeast to bread dough until I am ready to bake) I add the cooking temp and time to the label.
Rice and grains - I measure out grains with herbs and spices into a half pint jar, the label the jar with the wet ingredients.
Other cooking hacks I use, and probably you already know:
Spray measuring spoons with oil before measuring honey or molasses. The sticky stuff won't stick.
Wash flour off hands, and surfaces with cold water and it won't clump and get sticky.
Wear an apron. Saves clothes and cleaning.
Use a small spatula to get the last bit of yogurt, mustard, mayo etc out of the container.
Freeze butter wrappers and use then to grease cake pans and cookie sheets.
To warm cold eggs in a hurry, to make mayo or meringue, wash or place them in warm water.
Place a warm bowl over a stick of cold butter to soften quickly.
In the garden, I made up this planting tool so I don't have to bend over to plant peas, beans, corn... Works best with large seeds.
I took a PVC pipe and measured it to my height, I am 5.5 ft, so about 4 ft. I added a PVC T extension to the bottom of the pipe, so that the top of the T is in line with the pipe and the seeds can fall straight through. I added a short piece of pipe - maybe less than 2 inches - to the part of the T connector that sticks out from the pipe. To that I added an elbow connector. So now I have a long pipe with a sideways T at the end and the elbow off the T. To use, I gentlely push the long pipe into the soil of a garden row (I use a hoe to first make the row) then drop the seed through the long pipe. The elbow marks the spacing for the next seed. I place the long pipe in the mark left by the elbow. When I have seeded the row, I use the how to push soil over the seeds and tamp down.
I use pool noodles to keep my tall boots from flopping over.
I use a large fat Webster's dictionary as a knife block.
I put wheels on my old low hutch so I could move it as needed for extra counter space for canning and other kitchen projects.
I hope these help. 😁
