The tax rate there is the total of the 6.25% Illinois state sales tax rate, the .75% Will County Rate and 1.75% Joliet rate, for a total of 8.75% sales tax. Since Illinois is an origin-based state, you would charge all of your buyers in Illinois that 8.75% rate.
Place eggs in a large saucepan. Cover them with cool water by 1 inch. Slowly bring water to a boil over medium heat; when the water has reached a boil, cover and remove from heat. Let sit 12 minutes. Transfer eggs to a colander; place under cool running water to stop the cooking. Eggs can be peeled and served immediately.
This is where your timing needs to be precise. If the eggs sit in the hot water too long, they will overcook and end up with a green yolk. Extra large eggs will need 18 minutes to fully cook, large eggs need 15 minutes, and medium eggs need 12 minutes. Set a timer to prevent over or under cooking. For soft-boiled eggs (runny yolks, solid whites), let the eggs sit for 5 minutes less than the time needed to hard...MORE cook the egg.
