I went to buy guacamole ingredients today, and couldn't find a jalepeno. I found a serrano, which I know is hot, but I don't know how hot relatively. I know the heat develops over time in the guac, so I don't want to do it to taste. It would probably knock my socks off by tomorrow So, can anybody advise me on how to use the serrano in place of a jalepeno? One for one? Half a serrano to one jalepeno? One serrano to half a jalepeno? 3.14159 serranos per 6.02 x 10^23 jalepenos?
