  Today's puzzle was constructed by LA Times Crossword veteran Jerry Edelstein , whose last appearance here was on August 18, 2021 .  Today he appears in a MASTER 's TOURNEY , turning the last word of each themer into the first half of the reveal.  Here are the seeds:   20A.

Fan on a farm?: SWINE COOLER .  A riff on WINE COOLER , for those who use a thermometer to check their wine temperatures.  Very expensive.  We keep the REDS in the cellar because it's cool, and we keep WHITES and ROSÉS in the refrigerator.  27. Hors d'oeuvres for a horror movie?: SCREAM CHEESE . A take on CREAM CHEESE . Teri makes a delicious dish with cream cheese, cream, butter, shrimp, fresh peas, and pasta.  Yummy ! 49A. Surveillance snacks?: STAKEOUT FOOD .  A riff on TAKEOUT FOOD . Cops can get prett
