Related for Beitzah 32:9

If a holiday falls on the day before the Sabbath, one may not make an Eruv in relation to courts or an Eruv in relation to Sabbath areas. These are words of Rabbi. But the other sages say: One may make an Eruv in relation to courts, but not in relation to Sabbath realms. You can with bread make an Eruv for the Sabbath and with a cookery for the holiday. The cooking of which they spoke is considered even fried, even boiled, even colias, over which hot water was poured on the eve of the feast day.
