"It's a tsunami of blue out there."

That's the first thing John Cuddy said to us when we got out of the car last weekend at his Rush River Produce in Maiden Rock, Wis. Cuddy doesn't seem to be a man prone to exaggeration, so he's not kidding when he says that this year's blueberry crop appears to be one for the record books.

I've been visiting this nothing-else-like-it U-pick destination for more than a decade, and I've never witnessed anything that comes close to the abundance of this summer's output. To say that the farm's 10,000-plus plants are heavy with fruit is an understatement.

This summer is also unusual in that the crop is maturing on a stepped-up schedule.

"In 25 years, I've never seen so many berries, so early," said Terry Cuddy, John's spouse and fellow blueberry enthusiast. Again, she's not overselling. She directed me down to the rows of Nelson berries (a variety after my own heart), which usually mature in early August. Last weekend, many Nelson berries were already starting to turn blue. 

Yes, the picking has never been easier at the Cuddys' strikingly picturesque farm, where colorful, well-tended flower gardens give way to neat rows of bushes ("We've got nine miles of blueberries," is the farm's party line) cascading down rolling hills and melding into spectacular Rush River valley views. The abundance means that pickers don't have to go to too much effort to get their fill; with very little effort, three of us filled two boxes (one of them is pictured, top) in less than an hour, roughly seven pounds of summer treasure.

The Cuddys cultivate more than a dozen northern blueberry varieties, which translates into berries of varying sizes and flavors. They also have a small side business in currants (red, black and white) and gooseberries. 

The farm is roughly 70 miles southeast of the Twin Cities, and is open Thursday through Sunday, 8 a.m. to 2 p.m. Although the place is brimming over with berries, it's still best to call ahead and check on availability: 715-594-3648. Cost is $4.50 per pound (or $9 per pound for pre-picked berries), cash or check.

Pack a picnic lunch, or, if it's Friday, Saturday or Sunday, stop into Maiden Rock and enjoy inexpensive sandwiches or quiche on the front porch at the Smiling Pelican Bakeshop (one note: cash only). Don't miss a slice of one of baker Sandra Thielman's extraordinary pies. We made quick work of a fantastic buttermilk-lemon pie topped with blackberries and some of the farm's blueberries (pictured, below); my only regret of an otherwise perfect day is that we didn't buy a second slice. 


Once we got all those blueberries home (the gentle scent that filled the car was semi-intoxicating), I wondered if we'd gone a little overboard. But after handing out a few stashes to friends, I picked up a box of quart-sized freezer bags and jumped into the freezing process. 

It's easy. The first step is filling a small baking tray with a single layer of berries -- and taking a few moments to weed out the duds -- and freezing them for at least an hour, enough time to transform them into cold marbles.



It's a time-consuming and slightly awkward process -- fortunately, I've got a jelly roll pan that just squeezes within the confines of our side-by-side freezer. But in the end, it's better to take the extra step than simply freezing fresh berries by the bag; the berries won't be stuck together. I choose quart bags vs. gallon bags for a reason; it's more convenient to thaw only what's needed, and who ever needs an entire gallon of blueberries?

The fruits of our labors yielded 14 quart-sized bags, minus all the snacking (and baking, see below) that we did prior to filling the freezer. Not bad for 45 minutes work. 



I did manage to set aside a few fresh berries for some weekend baking. This coffee cake went fast. 



Judging from its popularity, I'll be making this recipe for months. It's a good thing I've got all those berries in the freezer. 



Serves 12 to 16.

For cake:

3 c. flour, plus extra for pan

2 tsp. baking powder

2 tsp. baking soda

Freshly grated zest from 1 lemon

12 tbsp. (1 1/2 sticks) unsalted butter, at room temperature, plus extra for pan

1 1/2 c. sugar

3 eggs

1 tbsp. vanilla extract

1 1/2 c. sour cream

1 1/2 c. blueberries, fresh or frozen

For topping:

1/2 c. chopped pecans

3 tbsp. ground cinnamon

3 tbsp. sugar

4 tbsp. (1/2 stick) melted butter


To prepare cake: Preheat oven to 350 degrees. Butter and flour bottom and sides of a 9- x 13-inch pan. In a large bowl, whisk together flour, baking powder, baking soda and lemon zest and reserve. In bowl of an electric mixer on medium speed, beat butter and sugar until light and fluffy, about 3 minutes. Add eggs, 1 at a time, beating well after each addition. Add vanilla extract and beat until combined. Reduce speed to low and add flour in thirds, alternating with sour cream and mixing until just combined; do not overmix. Gently fold in blueberries. Spread batter evenly into prepared pan.

To prepare topping: Sprinkle pecans evenly over top of batter. In a small bowl, combine cinnamon and sugar and sprinkle mixture over top of pecans. Evenly pour melted butter over top of cake, then run a knife through batter to allow butter to run down into cake. Bake until top is lightly browned and springs back from a light touch, about 45 minutes. Remove from oven to a wire rack to cool. Serve warm or at room temperature.
