Judging by social media, most people seem to be baking their way through this pandemic. But the local supermarket hasn't had eggs for a couple of weeks now. Our younger daughter's birthday is in two days, so we discuss the ethics of travelling to a different supermarket in search of eggs for a birthday cake. Does this meet the threshold of an 'essential journey'?

Our older daughter (a science nerd) pitches a possible solution: apparently blood has similar proteins to egg, and might make an effective egg substitute in a dark-coloured cake.

We reject this idea as ridiculous. But if push comes to shove, we can re-evaluate it tomorrow.
