It\u2019s best to remove the cap skin and the tubes before cooking. They have an OK flavour, I tend to dry and powder them and use them as a seasoning. To be honest they are better mushrooms available at this time of year.<\/p>\n<p>In Eastern Europe they tend to be blanched before cooking to remove the slimy coating.<\/p>\n<hr \/>\n<h2><strong>Known hazards<\/strong><\/h2>\n<p>Suillus mushrooms have been known to cause gastric upsets in some. Removing the caps and tubes reduces the risk but if it is your first time trying them, you\u2019re advised to taste a small piece and wait for 24 hours to see whether there are any adverse reactions.<\/p>\n<hr \/>\n<h2><strong>Potential lookalikes<\/strong><\/h2>\n<p>They could be confused with other Suillus species for example the <a href=\"https:\/\/totallywilduk.co.uk\/2021\/11\/30\/larch-bolete-suillus-grevillei-identification\/\">Larch Bolete (Suillus grevillei)<\/a> but this is generally more orange in colour, grows with Larch and has angular shaped pores.<\/p>\n<p>As with all Bolete\u2019s remember the rule \u2018Red or Blue, will make you spew\u2019. And you\u2019ll stay safe.<\/p>\n<hr \/>\n<h2><strong>Extra Notes from the foragers<\/strong><\/h2>\n<p>The Suillus genus is part of the wider Bolete family they are typically identified by growing with coniferous trees (particularly Pines), having slimy or greasy caps when moist and having large pore openings. Some are highly regarded by chefs but the majority are ignored due to the texture of the caps. I\u2019d rate them as OK and I do eat them if there\u2019s nothing around.<\/p>\n<p>The name Suillus comes from the Latin word \u2018sus\u2019 for pig, so Suillus means \u2018of pigs\u2019 in reference to their slimy caps.<\/p>\n<hr \/>\n<p><strong>Reference:<\/strong><\/p>\n<p><a href=\"https:\/\/en.wikipedia.org\/wiki\/Suillus_luteus\" rel=\"nofollow noopener\" target=\"_blank\">https:\/\/en.wikipedia.org\/wiki\/Suillus_luteus<\/a><\/p>\n<p><a href=\"https:\/\/www.first-nature.com\/fungi\/suillus-luteus.php\" rel=\"nofollow noopener\" target=\"_blank\">https:\/\/www.first-nature.com\/fungi\/suillus-luteus.php<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Slippery Jack \/ Summer \/ Autumn \/ Edible Scientific Name Suillus luteus Common Names Slippery Jack Family Suillaceae Habitat They form mycorrhizal relationships with coniferous trees, most often with Scot Pine (Pinus sylvestris).
