Avocado and broad bean mash

You can look at podding broad beans two ways: either as a great big bother not worth it, or as something wonderfully therapeutic to do with the radio or music on. It’s also a job very easy to outsource, if anyone is offering to help. Either way, the resulting dish is wonderful: lighter than an avocado-only guacamole and all the more lovely for it. The mash can be made in advance, if you like: it keeps in the fridge for a couple of days.
