I'll tell you what would be nice with this. Some horseradish, thinned with a little soured cream.

知道配什么正好吗？山葵用酸奶油调稀。

Mix the soured cream with ketchup.

【mix】把酸奶油和番茄酱拌在一起。

Besides ketchup, their slippery surfaces also aid the dispensing of products such as mayonnaise, and may help, too, with things like hummus and soured cream that have a thicker consistency and which usually come in tubs.

除了番茄酱，他们的光滑表面还能帮人们更畅快地涂抹蛋黄酱等产品。还有鹰嘴豆泥和酸奶油之类更粘稠和通常用盒子装的产品或许也用得着。
