Chapter 55: 4 & 5
The Order of Precedence of Blessings
4.If a type of food which requires the blessing borey pri ho'eitz or one
which requires the blessing borey pri hadomoh is placed before one,
together with a type of food which requires the blessing shehakol, the
blessings borey pri ho'eitz and borey pri hadomoh are given priority. They
are considered more important because they are more specific, including
only one particular type of food, while shehakol includes many types.
Even when one prefers the food which requires the blessing shehakol, one
should still grant priority to foods which require the blessings borey pri
ho'eitz and borey pri hadomoh.
5. The blessing borey minei mezonos takes precedence over the blessing for
wine. This [precedence] surely applies to the blessing hamotzi, which takes
precedence even over the blessing borey minei mezonos.
Accordingly, on the Sabbath and festivals, when one recites kiddish on
wine, one should cover the bread, so that it "should not see its shame,"
that the blessing on wine is being recited before it. Similarly, in the
morning, when one recites kiddish and then eats pastry, the pastry should
be covered during kiddish.
