=== perfect egg yolks === "Maybe I have a hangup on soft boiled eggs, but I’m deeply fascinated by how something simple as an egg can be transformed into such a wide range of textures. I’m talking about pure eggs – no other ingredients added. Playing around with temperature and time can result in some very interesting yolk textures – yolks that are neither soft nor hard, but somewhere inbetween." --Martin Lersch * http://blog.khymos.org/2011/04/18/perfect-egg-yolks/ * http://blog.khymos.org/2011/04/23/perfect-egg-yolks-part-2/ === temperatures === | **Proteins** | **Denaturation temperature (°C)** | | **From the egg white** || | Ovotransferrine | 61 | | Ovomucoïde | 70 | | Lysozyme | 75 | | Ovalbumine | 84,5 | | Globuline | 92,5 | | **From the yolk** || | LDL | 70 | | HDL | 72 | | Alpha livetine | 70 | | Beta livetine | 80 | | Gamma livetine | 62 | | Phosvitine | > 140 | | Yolk | 65-70 (because of LDL) | (Table 3. in "Molecular gastronomy: a scientific look to cooking", Hervé This) see also "Culinary Biophysics: on the Nature of the 6X°C Egg", César Vega, Ruben Mercadé-Prieto, 10.1007/s11483-010-9200-1 (paywalled online) === poaching === * field testing several ways to poach an egg > http://www.b3ta.com/features/howtopoachanegg/ === Some Science === * "The Science of Boiling an Egg" http://newton.ex.ac.uk/teaching/CDHW/egg/ * The science of "Unboiling" an egg http://phys.org/news/2015-01-chemists-unboil-eggs.html * ...and derivations http://newton.ex.ac.uk/teaching/CDHW/egg/CW061201-1.pdf
