Holy Mushrooms

Original publication date:

Aharon from Ramot asks:

My wife bought a can of mushrooms with a good hechsher (kosher certification). However, I was surprised to see that there was no mention of whether trumos and ma'asros had been separated nor was there any mention of sh'mittah. Could you please enlighten me?

Mushrooms may be popularly considered a vegetable, but they are really very different. They do grow on the ground, but not from the ground. They have no roots and take their nourishment from the moisture in the air. There is therefore no obligation to take trumos and ma'asros from mushrooms. For the same reason, they have no kedushas shvi'is and the prohibition of s'fichin does not apply to them. The correct berochoh (blessing) on mushrooms is shehakol, and not ho'adomoh. Nevertheless, when buying canned mushrooms one should ensure that they have a good hechsher for two reasons: (a) they are cooked with steam, which may previously have been used for non-kosher products, such as soup (b) there may be other ingredients which present kashrus problems. (Source: Minchas Yitzchok, Vol.8, No.99, from the Me'iri to Avodah Zoro 14b.)
