Heat. Outside, it's making us sweat and making castelfranco and other greens bolt. Inside, in WNYC's Studio 4, the heat of the 60-Second Stir-Fry lightning round of hard-hitting questions is making Brooklyn Grange's Anastasia Cole Plakias and Ben Flanner nearly come to blows.

The farmers of Brooklyn Grange talk about planting, growing and eating castelfranco, a bitter radicchio that is almost out of season. Try Brooklyn Grange's recipe for Orechiette with Castelfranco and Guanciale.

Walking down Vanderbilt Avenue in Brooklyn one weekend, I did a double take when I saw a little storefront selling mayonnaise. Just mayo? Does the condiment deserve such a spotlight?

Love, loss and how I swore — that's one of the ways I like to describe my tennis blog. Yes, dear readers, there's more to me than just radio and eating. I've got to work off the stress and calories somehow. 

But calories were not on the top of mind when I decided to create a blog bracket contest for the men's and women's draws of the French Open in Paris earlier this month.  I decided to offer a cake, baked by me, to the winner.

Brooklyn Soda Works puts a foodie spin on a much-maligned beverage by creating artisanal, seasonal soda from fresh fruit juice. Try out the company's recipe for an Apple & Ginger Dark 'n' Stormy.

It's sunny and warm outside, so we focus on wetting our whistle and keeping dangerous UV rays out of Mascot Cat's eyes in this week's 60-Second Stir-Fry.

Once again, we're tossing wild edibles into the 60-Second Stir-Fry, talking about burdock with forager Leda Meredith on this week's Last Chance Foods. But Meredith is a former dancer, and that's what got her sizzling on the hot seat for our 60-second lightning round of questions.

Forager Leda Meredith recommends burdock flower stalks as a delicious and easy-to-identify wild edible. Try her simple burdock stalk recipe.

Teresa von Fuchs, the coffee and espresso consultant for Dallis Bros. Coffee, thinks cold-brew coffee is unfairly getting a cold shoulder: "When you taste them side by side, I think both ways are equally good. Just different."

Fish farmer Christopher Toole talks about raising fish in plastic bins in the Bronx and how it could be the future of urban farming. Try his recipe for Pan Sautéed Tilapia with Invasive Weeds Pesto and Oyster Mushrooms.

Leave it to the 60-Second Stir-Fry's lightning round to render speechless someone who has a lot to say. Christopher Toole, the Bronx-based fish farmer who raises tilapia in plastic bins -- don't call them garbage cans! -- can talk a blue streak when it comes to urban farming and his vertically integrated farms. But he floundered (tilapiaed?) when it came to grueling questions like, "Taste you couldn't do without."

Farmer Keha McIlwaine of Queens County Farm Museum talks about growing spring leeks, and chef Cornelius Gallagher offers some advice on preparing the hardy vegetable. Try Gallagher's recipe for pan-roasted shrimp with glazed leeks, young coconut and yellow curry.

The inaugural Great GoogaMooga food and music festival last weekend is a reminder that greatness is neither self-bestowed nor assumed. You have to earn it.

From the looks of things during the event in Prospect Park and the critiques dribbling in on Twitter and Facebook (internet and cell phone service was abysmal on Saturday, when I went), GoogaMooga has a way to go before it can be called "great."

This Sunday, New Amsterdam Market brings fresh seafood back to South Street with the Gathering of Fisheries Event. Commercial fisherman Vinnie Calabro talks about what's in season and the future of Jamaica Bay. 

If you can't stand the heat, don't sit still for the 60-Second Stir-Fry. This week’s Last Chance Foods guests, Vinnie Calabro and Robert LaValva, may have hooked a lot of fish in their time, but when confronted with the lightening round of questions they were left fishing for answers.

The 99% may not have been able to set up camp in the empty lot bordered by Canal Street, Varick Street and Sixth Avenue, but now they can buy tamarind duck sliders and other food cart goodies there.

Starting this week, Tuesday thru Thursday, from 11 a.m. to 3 p.m., the lot will open its chain link fence and hosts a changing roster of food trucks. There's a little stage, too, for bands to serenade hungry workers on their lunch breaks. 

There's a strong DIY wind blowing through Brooklyn, as a recent New York Magazine article about the borough's artisanal food makers noted. It blew through my kitchen window the other night.

Forager and author Tama Matsuoka Wong explains how to safely eat stinging nettles and how they may help with seasonal allergies. Try a recipe for Nettle and Asparagus Pizza from the book she wrote with Daniel chef de cuisine Eddy Leroux.

Our Last Chance Foods guest this week, Tama Matsuoka Wong, forages and eats stinging nettle, so we knew she wouldn't break a sweat when confronted with the Stir Fry's lightning round of tough-as-overgrown-knotweed questions.

Knotweed is an invasive pest hated by many, and the most effective way of getting rid of it may also be the most delicious. Urban forager Marie Viljoen talks about finding, cooking and eating knotweed. Plus, try her recipe for Knotweed Soup.
