Segment 1 (Deep Dive)

Introduction

David Rowe, VK5DGR, in an electrical engineer living in Adelaide, South Australia. His mission is to improve the world – just a little bit. He does this through developing innovative hardware and software for telephony. This hardware and software can help many people, for example through improved, low cost radio communication for poor people in remote areas of the world. So rather than making money from his technology, he gives it away.  He has a PhD in signal processing, and has proven skills in low bit rate speech compression and HF modems, with a focus on combining these technologies for digital voice over HF radio applications.  Projects you know him for are FreeDV, Codec2, and SM1000 Digital Voice Adapter.

This Weekend in Hedonism (Segment 3)

Cheryl’s Recipe Corner

Baja Fish Taco Sauce

1 cup mayo

1/2 cup sour cream

5 cloves garlic

1 tablespoon lime juice

1/4 teaspoon cayenne pepper

1/4 teaspoon (slightly heaping) salt

Citrus Slaw

1/4 cup fresh-squeezed orange juice

1 tablespoon lime juice

Pinch salt

Pinch black pepper

1 teaspoon agave or honey

1/4 cup olive or avocado oil

4 cups thinly shredded green cabbage

2 cups thinly shredded red cabbage

1/4 cup cilantro leaves, roughly chopped

Fish Tacos

1 1/4 pound cod, cut into short strips or bite-size chunks

Salt

Black pepper

Pinch cayenne pepper

1/2 teaspoon ground cumin

1/2 teaspoon ground coriander

1/2 teaspoon granulated garlic

1 1/2 cups all-purpose flour

1 (12 ounce) bottle/can of beer

Vegetable oil, for frying (about 3 cups)

Corn or flour tortillas, warm (about 24 tortillas so you can double up on each taco) - use “Fajita Size” if you’re using Flour tortillas

Cilantro leaves, lime, sliced radishes, for garnish

Shredded Cheese (Mexican Blend or Cheddar, optional)

Preparation

Prepare your spicy garlic-lime mayo by placing all ingredients into a food processor and processing until smooth and combined; pour into a bowl, or into a squeeze bottle, ideally.

Prepare your citrus slaw by whisking together the orange zest, orange juice, lime juice, pinch of salt and pepper, agave or honey, and oil until well-combined (you can also shake these vigorously in a small mason jar for convenience), and set aside for a moment; add both of your shredded cabbages and the cilantro into a medium-size bowl, and toss the dressing you just made with the cabbage/cilantro; keep cold.

To prepare you fish tacos, add your cod pieces to a bowl and season with a couple of pinches of salt and pepper, plus the cayenne, cumin, coriander and garlic powder; allow them to marinate for a few minutes while you get your oil ready and prepare to fry.

Prepare a baking sheet with foil and a place a wire rack over top (if you have one) to hold the cod once it’s been fried; next, add enough oil to a deep pan or a medium-size pot so that the fish can be submerged when you fry it (about 3 cups), and bring it to 365°.

While your oil heats, whisk together the flour with a couple of pinches of salt and pepper, and slowly pour in the beer and whisk just until smooth; once the oil is hot, dip the pieces of cod into the batter and fry in batches (it took 3 batches for me) for a 3-4 minutes or until golden-brown.

To assemble, add a couple of pieces of the fried cod to the bottom of a couple of corn tortillas, top with a generous amount of the slaw, add in some radishes (if using), drizzle the spicy garlic-lime sauce liberally over top, and finish with some cheese, extra cilantro and a squeeze of lime.

Russ’s Drink Corner

Aberfeldy 12

Bill’s Whatever Corner

New Age White

9% ABV

Blend: 90% Torrontes, 10% Sauvignon Blanc

Acidity leads to soft, semi-sweet and slightly effervescent flavors and mouth feel. It is an extremely refreshing, vivacious and sensual wine.

Should be served well-chilled as an aperitif or dessert. Also tastes great with spicy Thai, Indian, Chinese or Japanese cuisine.

Music (Segment 4, Optional)
