What hides this stereogram?

A minister who was very fond of pure, hot horseradish always kept a bottle of it on his dining room table. Once, at dinner, he offered some to a guest, who took a big spoonful.The guest let out a huge gasp. When he was finally able to speak, he choked out, "I've heard many ministers preach hellfire, but you are the first one I've met who passes out a sample of it."
