Seeing Red

Don’t risk sleeping in on a Saturday this month, for arriving late at the farmers’ market might cause you to miss the debut of one of spring’s edible blessings.

The market is coming into full bloom, beginning with truckloads of cool-weather crops like locally-grown asparagus, tender artichokes, fava beans, celery, peas-in-the-pod, and super-sweet sugar snap peas. Fragrant strawberries proliferate, followed closely by juicy little cherries. But don’t stop there. Look closely and you’ll also find a lesser heralded shade of red—one that always triggers childhood memories for me.

My father was the gardener in our family, and maintained a good-sized patch of rhubarb in the backyard. As kids we considered this oddly-named plant very old-fashioned. While modern American moms threw together a Tunnel of Fudge Cake or some other gooey concoction, our Irish mother would bake a rhubarb pie. From scratch. You can only imagine our embarrassment.

By some cosmic twist of fate I ended up with a man who also happened to love rhubarb, so every spring I would dream up new ways to serve it. Rhubarb in the morning. Rhubarb in the evening. Rhubarb at suppertime.ThinkstockPhotos-177087863-1

I once made the following recipe for a friend’s annual potluck, and the fresh-outta-the-oven aroma wafting from the trunk kept us salivating all the way across the Golden Gate Bridge.

When The Cookbook Author arrived at the party, friends excitedly asked what I brought for dessert. Most could barely conceal their disappointment when I answered, “Rhubarb Crisp.”

After a leisurely lunch—and fittingly fortified by several glasses of wine—each of the biggest skeptics politely sampled a tiny spoonful of the crisp—paired with a huge scoop of vanilla ice cream. And then I watched them return to the buffet for more…this time omitting the ice cream. And then suddenly the crisp was all gone, and the host was good-naturedly complaining there wouldn’t be any leftover for his breakfast the next morning. This was followed by plenty of comments from incredulous guests saying things like, “I guess I do like rhubarb…” and, of course, requests for the recipe.

Instead of a more traditional oatmeal crumb topping, this version blankets sweet-tart rhubarb with a buttery-rich, almost cookie-like layer made all the better with the crunch of California walnuts and a hit of ground cinnamon.

The moral of the story is to keep an open mind. Cherries and berries are not the only way in which spring casts its rosy glow on our lives. If you can read this you are no longer 3 years old; so no matter how icky the idea of something may sound to you, trust Mother Nature. She only deals in the good stuff.

Rhubarb Revelations
-The thick, celery-like stalks of rhubarb can reach up to 2 feet long. The leaves of the plant must be discarded before cooking, as they contain oxalic acid and are therefore toxic. (Relax. For this very reason, rhubarb is never sold with the leaves attached. I just threw in this warning for any home gardeners out there.)

-A good source of fiber and Vitamin A, flavorful field-grown rhubarb has cherry-red stalks and green leaves. Its peak season is April through June.

-Hothouse-grown rhubarb, available year-round in many supermarkets, has a milder flavor, yellow-green leaves, and pinkish stalks that cook up to a not-so-appetizing gray…which is why many recipes suggest combining it with strawberries or a few drops of red food coloring.

-Choose crisp, brightly colored stalks with fresh-looking stems. To store, refrigerate in a plastic bag for up to 3 days. Buying rhubarb at the farmers’ market ensures freshness…making no competition for the lonely stalks of limp, dry, or bruised rhubarb that languish in supermarket produce aisles.

-Rhubarb has undergone some gender re-assignment over the years: Although considered a fruit, botanically it’s really a vegetable.

-Known as “pie plant” in some areas, rhubarb is always combined with a fair amount of sweetener to tame its natural tartness.


For the Cinnamon-Walnut Topping
1 1/4 cups coarsely chopped California-grown walnuts
2 sticks (8 ounces) unsalted butter, softened to room temperature
1/2 cup (packed) dark or light brown sugar
1/2 cup granulated sugar
1 3/4 cups all-purpose flour
3/4 teaspoon ground cinnamon
1/4 teaspoon baking powder
1/8 teaspoon fine sea salt

1. Preheat the oven to 350 degrees. Spread the walnuts on a baking sheet and bake, stirring once or twice, until lightly browned and fragrant, 5 to 7 minutes. Let cool.
2. Using an electric mixer or a wooden spoon, mix together the butter, brown sugar, and granulated sugar until creamy and well blended.
3. In medium bowl, combine the flour, cinnamon, baking powder, and salt. Whisk gently to blend. Gradually beat the dry ingredients into the butter mixture until just blended. Stir in the walnuts.
4. Loosely pack the mixture into a bowl or a heavy-duty plastic food storage bag. Freeze until very firm, at least 4 hours or as long as 1 month.

For the Rhubarb Filling
3 pounds fresh California-grown rhubarb
1 cup plus 2 tablespoons granulated sugar
3 tablespoons all-purpose flour
Dash of salt
Finely grated zest of 1 California-grown orange
1 tablespoon fresh orange juice

1. Preheat the oven to 350 degrees. Grease a 2 1/2- to 3-quart shallow baking dish. Rinse the rhubarb stalks under cold running water and discard any leaves. Cut stalks crosswise into pieces about 3/4-inch thick. (You’ll have 9 to 10 cups.)
2. In a large bowl, mix together the sugar, flour, salt, and orange zest. Add the orange juice and rhubarb, tossing to coat with the sugar mixture. Scrape into the prepared baking dish.
3. Use a large knife to chop the frozen Cinnamon-Walnut Topping; then scatter the chunks and bits over the fruit. Bake until the topping is golden and the rhubarb is tender and bubbly-hot, 45 to 55 minutes. Let cool on a wire rack. Serve slightly warm, at room temperature, or lightly chilled. Serves 10 to 12.

Waste-water & Daylilies

Q. What additional chemicals would I have to mix with grey water in order to use it on trees and large shrubs? I vaguely remember something about zinc and iron from back in the nineties.

A. It’s not necessary to supplement grey water with any additives when using it to water outside plants. Grey water is defined as “Untreated wastewater from clothes washers, showers, bathtubs, bathroom sinks, and laundry tubs.” The untreated wastewater from kitchen sinks, dishwashers or toilets, referred to as Black Water, is prohibited. Most home plumbing systems can be modified in order to capture grey water, but you’ll need to check the requirements in your local area. Vegetables can be watered with grey water as long as the water doesn’t come in contact with the edible parts. You will have to change the laundry and bathing products you use to those that are plant friendly. No bleach, dyes, bath salts, cleanser, shampoos with unpronounceable ingredients, and no products containing boron.
Grey water needs to be used quickly as it’s recommended that you don’t store it for more than twenty-four hours. Watering basins around plants is desirable as it minimize run off and acts as a percolation basin. The utilization of Grey water is advantageous for sustainable ecosystems but it’s not right for everyone. You’ll find more information on grey water at

Q. Is it too late to divide and transplant my Daylilies? Is the green and healthy foliage normally cut back after they finish blooming? If so how far back are they trimmed?ThinkstockPhotos-465859544

A. Unless you really had too, I’d probably wait and not move the plants now. Daylilies are best relocated and divided October through the end of March. I wouldn’t cut the foliage off after flowering. Instead, I’d wait until the winter months and then cut the foliage off at the ground, as they do get shabby looking from the winter storms and cold. It could be done early or later as it doesn’t matter to the plants. I prefer later as the green foliage is far more visibly pleasing then the short stubble left after the ground level pruning. Those plants moved or divided in the fall and winter months produce no new growth until the following spring. Before transplanting, I would cut the foliage back to the ground as it makes it easier to move the plants. Using a round nose shovel, sever the lateral roots around the clump then gently lift the clump out of the ground. Next, you slice the clumps in half or quarters depending on their size with a pruning saw, hand shears or shovel. Before replanting remove any of the lose debris from the clumps. I would dig a hole that is twice to three times as wide as each clump and add plenty of homemade compost, soil conditioner or blended mixes to the native soil. Also, add a handful of starter fertilizer to the bottom of the hole. Moving and dividing Daylilies isn’t difficult and you have a high success ratio.
