For cakes I like using leaves brushed with chocolate.
Wash some green leaves (preferably something non toxic), dry, chill in fridge, brush with melted chocolate, chill again, peel the leaf from the chocolate.
Garlic will repel aphids on some plants, but other aphids will feast on garlic, it depends on the climate. A spray of water with a little soap and a pinch of salt is lethal to most aphids. The soap helps make it stick.
Garlic spray is my goto for dealing with pests from bugs to cats. Most things hate it, it smells like hell.
Put a few cloves in a spray bottle, leave it in the sun for a few days, add a pinch of salt and a little soap.
Though access is limited, they do have the tech thanks to their friends to the north. I can’t find the link, but they have their own Great Firewall implementation
I have actually never broken one. Peel the leaf from the chocolate, not the other way round. The darker the chocolate the more brittle it will be I think. As long as the leaves aren’t huge I don’t think you will have a problem.
