A normal range for blood urea nitrogen is generally 8 to 24 mg/dL for adult men (2.86 to 8.57 mmol/L) and 6 to 21 mg/dL (2.14 to 7.50 mmol/L) for adult women. However, urea nitrogen levels vary by age. Infants have lower levels than other people do.
Fortunately, freezing zucchini and other summer squash is a snap: All you do is cut it into half-inch slices, blanch it in a pot of boiling water for three minutes, transfer it to a bowl of ice water to cool, drain it, and bag it.
PLACE remaining 1/2 cup flour in plastic or paper bag. Cut zucchini into 1/4-inch diagonal slices. Rinse and pat dry. Shake slices in flour to coat. 3. MELT shortening to a depth of 2 to 3 inches in a deep fryer or deep saucepan; heat to 375ÂºF. Dip floured zucchini in chilled batter. Let excess drip back into bowl. 4. FRY a few at a time in hot oil 4 to 4 1/2 minutes, or until golden brown, turning several times. Drain on paper towels.
