Birria de Res Kit

A direct freezer port of the musculo_birria-de-res.md recipe. The chile paste is the only fiddly part of birria; bag it once, freeze it with the meat, and the cook-day work drops to “dump and press a button.” 50 minutes later: tacos.

The chile paste also doubles as a freezer staple on its own — make a big batch, freeze a portion in this kit, freeze the rest in ice-cube trays for adobo, marinades, and quick chicken stews. One Sunday afternoon = months of Mexican base.

Heat: 3/5. Building heat from three chiles. See related recipe for tame-it variants.

Bag contents

• 1.5 kg músculo (beef shin), bone-in if possible, cut into 6-8 chunks
• 1 large onion, halved
• 4 bay leaves
• The chile paste (made and added — see below)

Chile paste (make and freeze; about 500ml total, use 250ml per kit)

Same as the related recipe — full instructions there. Quick version:

• 4 dried guajillo chiles (or middle-path: 2 tbsp paprika doce + 1 tsp paprika defumada + 1 dedo-de-moça seca; or see Pressure Cooker/chile-substitution-guide.md)
• 2 dried ancho chiles (or middle-path: 1 tbsp paprika doce + 1 tbsp tomato paste + 1 ameixa preta (prune) blended in for the raisin-sweet quality)
• 1 dried chipotle morita (or 1 tbsp Cepera Chipotle sauce — most reliable substitute as Cepera’s chipotle is genuinely smoky)
• 4 garlic cloves
• 1 tsp cumin seeds, toasted
• 1 tsp Mexican oregano
• 4 cloves
• 1 cinnamon stick (3cm), broken
• 2 tbsp white vinegar
• 2 medium tomatoes
• ½ tsp salt

Toast and soak chiles 15 min. Blend with everything else + 50ml chile soaking liquid until smooth. Strain through a sieve for silky texture. Use 250ml per kit; freeze the rest in 100ml portions for future kits or other dishes.

Prep day (Sunday assembly — ~5 min once chile paste is made)

1. Pat beef dry. Salt the beef chunks lightly (about ½ tsp salt total — most seasoning is in the paste).
2. Bag. Place beef in 2-gallon zip bag. Add halved onion, bay leaves.
3. Add chile paste. Pour 250ml of the prepared chile paste over the beef. Squish the bag to coat every piece.
4. Press out air. Vacuum seal or squeeze flat.
5. Lay flat to freeze.
6. Label (see below).

Birria de Res — 2026-05-10
Serves 6
Cook: PCC20 P14 (Carne) 50 min thawed / 60 min frozen
Add 500ml beef stock + frozen bag → cook
For tacos: see related card musculo_birria-de-res.md

Cook day

Pressure cooker (PCC20, P14 — Carne)

From frozen (the standard kit usage):

1. Dump frozen bag contents into PCC20.
2. Add 500ml beef stock (or water + 1 stock cube).
3. P14 (Carne), adjust to 60 minutes, high pressure. Natural release fully (15 min).
4. Open, shred meat with two forks. Skim the orange fat off the consommé and reserve in a small bowl — taco gold.

From thawed:

1. Defrost in fridge overnight.
2. Same method but 50 minutes, natural release.

Slow cooker variant (P6 — Cozimento Lento) — also works

If you’d rather slow-cook:

1. Dump frozen kit + 500ml stock in PCC20.
2. P6 (Cozimento Lento), 8h. (Use Programar Preparo for delayed start if you want.)
3. Result is slightly different — meat is more falling-apart, sauce slightly thinner. Both versions are excellent. Reduce the consommé in a small saucepan if you prefer it thicker.

Tame it (drop to heat 1-2)

The chile paste is where heat is set. Adjust before bagging — the kit freezes at whatever heat you make.

• Heat 2: use 2 guajillo + 1 ancho + 0 chipotle in the paste. Dish stays clearly Mexican but mellows.
• Heat 1: use 2 guajillo only, no ancho or chipotle, plus 1 tbsp paprika doce in the paste. Retains flavor depth, drops heat dramatically.

You can also make a single big paste batch at the regular heat (3) and split it: half goes into hot kits, half gets diluted with extra paprika doce + 1 tbsp tomato paste for milder kits. Label clearly — once frozen, you can’t tell hot from mild without cutting open the bag.

Sub: bottled chiles only

If you can’t find dried Mexican chiles at all, replace the chile paste ingredients with this version (same yield, ~500ml):

• 3 tbsp Cepera Mexicano + 1 tbsp Cepera Chipotle + 1 tbsp paprika doce + 1 tbsp tomato paste
• Plus everything else from the chile-paste list except the chiles themselves (garlic, cumin, oregano, cloves, cinnamon, vinegar, tomatoes, salt)
• Reduce salt to ¼ tsp (Cepera sauces are already salted)
• Skip the toast-and-soak step — there are no dried chiles to prepare. Just blend everything together.

Result: ~80% as good as the dried-chile version. You lose the layered fruity-smoky-earthy complexity of three different chiles, but it’s still a great kit-version birria. See Pressure Cooker/chile-substitution-guide.md for the full mapping if you want to mix-and-match.

Serving

Quesabirria tacos (the iconic version):

1. Heat a skillet over medium-high.
2. Dip a corn tortilla in the reserved orange fat (both sides), place in skillet.
3. Top with grated Oaxaca cheese (or low-moisture mozzarella), then shredded birria.
4. Fold and fry until crisp on both sides.
5. Serve with: chopped white onion, fresh coriander, lime wedges, and a small bowl of consommé for dipping.

As a stew (heat 3 night):

• Bowl of broth + meat
• Warm tortillas to dip
• Lime + chopped onion + coriander on the side

Notes

• Make 4-6 kits at once. The chile paste is the time-consuming part; once it’s made, bagging additional kits adds 2 minutes per kit. Three Sundays a year of birria-prep covers a lot of weeknights.
• The chile paste freezes for 6+ months in ice cube trays; pop into freezer bags once frozen.
• Bone-in músculo helps but isn’t critical. Boneless works in this kit.
• Why no salt added to the kit? The chile paste already has salt. Taste at the end and adjust.
• No sauté step on cook day. Unlike the from-scratch recipe, the kit version skips the “fry the chile paste 3-4 min” step that develops the brick-red color. Acceptable trade for the convenience; the long pressure cook does similar work. If you want the deeper color, do a 5-min P5 (Refogar) after pressure release: drain meat, set sauté, reduce sauce 5 min until brick-red, return meat.
• Reheats well — leftover birria meat in jus reheats brilliantly. Keeps 4 days in fridge.
• Cross-reference: see musculo_birria-de-res.md for the from-scratch single-session recipe and full taco method.
