Heat oil in a deep pan or kawali over medium heat at 180°C/350°F. Once the oil is hot, add minced garlic (bawang) and cook for 1 minute until it turns light golden brown (ginintuan ang kulay). Watch carefully as garlic burns quickly.
Add the finely diced onions (sibuyas) to the golden garlic. Cook for 2-3 minutes, stirring occasionally, until the onions become translucent (malinaw ang kulay). The onions should be soft but not browned.
Add the ground pork (giniling na baboy) to the pan. Using a wooden spoon (sandok), break up any large lumps of meat. Cook at 175°C/350°F for 7-8 minutes until the pork is nicely browned (lutong-luto). You want the meat to develop a good color for better flavor.
Sprinkle ground black pepper (paminta) over the browned meat and stir well. Add the shrimp paste (bagoong alamang) and cook for another minute, stirring to distribute it evenly throughout the meat.
Add the finely chopped bird's eye chilies (siling labuyo). Start with fewer chilies if you prefer less heat – you can always add more later. Remember, authentic gising gising should wake up your taste buds (dapat nagigising ang panlasa).
Pour in the fresh coconut milk (kakang gata). Reduce heat to medium-low (165°C/330°F) and bring to a gentle simmer (pakuluan ng dahan-dahan). Never let it reach a rolling boil as this can cause the coconut milk to separate. Cook for 15-20 minutes, stirring occasionally, until the sauce begins to thicken (lumapot ang sabaw).
Add the chopped green beans (Baguio beans or sitaw). Cook for 5-7 minutes until they are tender-crisp. The beans should still have a slight crunch when bitten – overcooked beans will become mushy (malambot).
Taste and adjust the seasoning. Add more bagoong alamang if needed for saltiness, or extra chilies for heat. If the sauce is too thick, add a small amount of coconut milk. If too thin, simmer for a few more minutes.
Transfer to a serving bowl (mangkok) and garnish with chopped green onions (dahon ng sibuyas) and fried garlic bits (sinangag na bawang) if desired. Serve immediately while hot with steaming white rice (mainit na kanin).
For any leftover gising gising, let it cool completely before storing in an airtight container. It will keep in the refrigerator for up to three days. When reheating, use medium-low heat (160°C/320°F) and stir gently, adding a splash of coconut milk if needed to restore the creamy consistency.
