Tip for preparing avocados....
To slice avocados for salads or guacamole, split them in half, remove the pit by whacking it with the heel of your knife and twisting it out, then slice it directly in the skin using the tip of a paring knife or chef's knife. When you then scoop it out with a spoon, you'll have slices ready to go, with less mess than trying to fiddle with slippery peeled avocado a cutting board.
