Winter Sowing

If you haven't tried winter sowing, you're in for a treat.  This method is especially good for sowing herbs and greens.  Winter sowing is basically sowing seeds in the bottom of a milk jug during the winter, setting the milk jugs outside for the winter and leaving them there until the seeds germinate in Spring.

Growing Tips

• If the plant sends up a stalk instead of forming a head, cut off the stalk at ground level to encourage the formation of a new head.
• The bitter flavor is often due to hot weather.

Harvesting Radicchio

As soon as heads are firm and compact.
Radicchio matures in approximately 3 months.  It should be picked when it's mature, but not old.

Using Radicchio

• Eat fresh or cook like Spinach.
• Core out the small heads and remove the center to create leafy bread.
• Radicchio's bitter flavor pairs well with the acidic sweetness of Balsamic Vinegar.
• Salt will counteract the bitter flavor and draw out the high sugar content.

Storing Radicchio For Later Use

Although tender green-leafed plants, like lettuce, cannot be preserved well, the thicker green-leafed plants can be.

Fresh

• Clean and pat dry.  Bundle stems lightly, place on a paper towel (to absorb moisture) and wrap in a plastic bag.  Keeps in refrigerator for 10 days.

Freezing for Later Use in Chilis, Soups, Sauces, and Casseroles.

• Steam or saute' leaves, chop them and store in freezer bags.
• Puree with water and freeze into ice cube trays.
• Clean and dry the leaves and store in quart size freezer bags.
• Frozen leaves will keep for 6 months.
• Blanching the leaves for two minutes will extend freezer storage to 14 months.
