Anchovy butter is anchovy fillet pounded in mortar with butter and then passed through a fine sieve.

凤尾鱼黄油是将凤尾鱼片与黄油一起在研钵中捣碎，然后通过细筛。

Probably doesn't go that far because I need to also combine it with anchovy sauce which is that then mixed with anchovy butter and garnished with dice of anchovy fillet.

可能不会做到那种程度，因为我还需要把它和凤尾鱼酱混合在一起，然后和凤尾鱼黄油混合，再用凤尾鱼片装饰。
