You may be able to freeze them and use them later although I think egg whites freeze better than yolks. I have some cookie recipes that use just the yolks. I’ll often save up the whites from a cookie recipe in the ice cube tray in the freezer and when I get enough, make angel food cake with it. Was surprised, but frozen egg whites fluff/rise very well in angel food recipes. Cold egg whites can easily be whipped and they don’t need to be at room temperature. They just need to be defrosted You can also use yolks in omelette or crepe recipes.

That’s why we specifically mentioned Fediverse and FOSS alternatives to get the word out about Software Freedom Day here: https://wiki.softwarefreedomday.org/SFDMarketingSites The DFF board discussed this topic and wants to continue to reach out to people who don’t know about FOSS and the Fediverse. So, we are trying to meet them where they are and let them know about the benefits of using FOSS. Also, one of the groups did a talk on switching from X to Mastodon: https://mobilizon.fr/events/1ab64af3-b99e-473d-87da-7ad07497ab41 If you have suggestions for the web site, please join the SFD discussion mailing list and add your input. The new DFF board will be redesigning the entire site for next year, but did not have time to do so for the 20th edition of Software Freedom Day. Their main goal was making sure that we still had a Software Freedom Day this year after the old board stepped down.
