title: "Which Coaster Material Should You Buy?"
lead: "When in doubt, buy a cork set: it handles hot mugs and iced drinks alike, costs little, and is cheap to replace once stained. If condensation puddles are your main problem, choose diatomaceous earth instead."
recommendation:
  name: "A 6-pack of cork coasters"
  reason: "One material covers coffee through iced drinks, and six pieces are enough for guests. They're cheap enough to toss when stained. Add two diatomaceous-earth coasters for sweaty summer glasses and you're fully covered."
