Guar gum, a plant colloid, costs less than agar and is better suited for growing thermophilic bacteria, but is also more difficult to handle, being more viscous and less transparent. The bacterial polysaccharide xanthan is cheaper as well but forms weaker jellies that, as with carrageenan, might result in puncturing its surface. Other colloids, like alginate (from brown seaweed) and gellan gum (from a bacterium), don’t set solely based on temperature and require additives for gelation. These additives might interfere with microbial growth and make the preparation of those jellies less handy than agar plates.
You'll hear that phrase a few times throughout DTF St. Louis, a darkly comedic miniseries from HBO and creator Steven Conrad (Patriot). The show examines the intertwined lives of three friends, diving beneath their seemingly normal exteriors to prod at the desires and fantasies they hope will drive away their middle-age malaise. Along the way, there's an affair, a murder, and a wildly named hookup app called DTF St. Louis.
