* If you do not want your guacamole to be too spicy, chop the chili and remove the seeds. Always ear gloves when working with chilies and remember not to touch your eyes and mouth with your hands. Use a separate knife and cutting board and wash them well.
* Adding a few drops of lime juice to your guacamole will stop the avocado going brown; leaving an avocado stone in the bowl until you are ready to serve will also do the trick.
* If the chili proves hotter than you anticipated and your lips and tongue start to burn, lick up some grains of salt for relief.
